Implicit Interfaces and the Web

The best interface to software might be doing nothing at all. Implicit interfaces are gaining mindshare. This is not a new idea. Amazon improves your experience based on your habits, for example. Google increasingly employs subtle, personal weighting of our search results. In The Implicit Web, Alex Iskold talks about the services of Amazon, Google, and Last.fm. All of them take advantage of the implicit actions of their users. Last.fm lets us track, publish, and find songs we listen to and like, and after installation, I forget it most of the time I use it.

Implicit Today

A number of services have risen that really should be implicit, but are not. This might be caused by implicit interfaces' very nature of being unseen. Although they can be wonderful ways to interact with our networks, they are difficult to deploy. Developing the algorithms to translate user behavior into user interaction, without hindering the user experience, can be difficult. Even coming up with an idea for employing implicitness is difficult.

The ultimate implicit application might be Google, when taken in terms of number of users. Their intuitive Page Rank system turns millions of web pages interlinking between one another and turned it into a social ranking system. Digg, reddit, and their clones are hot news these days; however, we can't deny that they have done little more than turn what was implicit into something explicit. The change has good and bad qualities. An ironic note: Google seems completely unimpressed with social services, being the only major player expressing no interest in a service like social bookmarks. At least, this might appear to be the case, at first glance. However, when we take note that Google's entire business is built on the idea of utilizing the links on our web pages as votes, we find they were ahead of the game and have the largest social bookmarking site on the internet. The only missing features are associating the websites with actual people.

Why the Explicitness

If Google were so successful with the first massively deployed implicit interface, why would sites adapt the pattern into explicit voting systems? The migration from searching to sifting is a probable cause. The original Google model works great for mostly static content. Asking the popular search engine "What's new?" is not easy, and this is an angle explicit services employ. Social networks are nothing new, but the personal and explicit aspects are newly pushed. A search engine tells you which webpages are popular, but thinks knowing who agrees is less important. They also have a hard time distinguishing between things you like and things you do not like.

Implicit Tomorrow

We need to evaluate what makes a good system, which explicit interfaces can become implicit, and what naturally implicit features to improve. Embracing the implicit areas leads to a higher level of user involvement, because they can be involved when they are unaware of it. However, making the user aware of the affects of their implicit interactions might be exactly the sort of thing the user needs to understand these services are actually there and valuable. There is little market for sites that asks you manually rank books and movies and recommend more to you. Amazon made its business on doing just that, because it takes information automatically and makes it obvious to the user what value they are getting. I routinely buy books from my Amazon page, because I know my habits are tuned it into a great place for me to find what I need. The implicit is there, but I explicitly take advantage of it.

On Pruning Your Passions [MOVED]

We live in a hobby-rich world. There is no shortage of pastimes to grow a passion for. There is a shortage of one thing: time to indulge those passions. If you're someone who pours your heart into that one thing that makes your life worthwhile, that's a great deal. But, what if you've got no shortage of interests that draw your attention and you realize you will never have the time for all of them?

If I look at all the things I'd love to do with my life as a rose bush I'm tending, I realize that careful pruning is essential for the best outcome. This is a hard lesson to learn, because it can mean cutting beautiful flowers and watching the petals fall to the ground to wither. It has to be done.

I have a full time job that takes a lot of my mental energy. I have a wife and a son and family time is very important in my house. I try to read more, and I want to keep up with new developments in my career, and I'm trying to make time for simple, intentional relaxing t…

The Insidiousness of The Slow Solution

In software development, slow solutions can be worse than no progress at all. I'll even say its usually worse and if you find yourself making slow progress on a problem, consider stopping while you're a head.

Its easy to see why fast progress is better: either you solve the problem or you prove a proposed solution wrong and find a better one. Even a total standstill in pushing forward on a task or a bug or a request can force you to seek out new information or a second opinion.

Slow solutions, on the other hand, is kind of sneaky. Its insidious. Slow solution is related the Sunk Cost Fallacy, but maybe worse. Slow solutions have you constantly dripping more of your time, energy, and hope into a path that's still unproven, constantly digging a hole. Slow solutions are deceptive, because they still do offer real progress. It is hard to justify abandoning it or trying another route, because it is "working", technically.

We tend to romanticize the late night hacking…

Finding "One Game A Month"

I was really excited about the One Game A Month challenge as soon as I heard about it.
For about two years I've struggled in fits and starts to make my way into game development. This hasn't been productive in any of the ways I hoped when I started. Its really difficult to be fairly experienced as a developer, which I believe I am in my day job as a web developer, while struggling really hard at an area in which your experience just doesn't exist.
Its like being a pilot who doesn't know how to drive.

But this challenge provided a new breath to this little hobby of mine. It gave me a scaffolding to experiment, to learn, to reflect on finished projects. I had spent far too much time on game projects that stretched on far past their exciting phases, bogged down by bad decisions and regret.
And it has worked.
I have a lot to learn. I have a lot of experience to gain through trial and error and mistake and discovery. I have a lot of fun to be had making more small games t…
