When one browses to MindMeister and looks at the nicely designed page, the user will notice a nice screenshot of the service. This is not a screenshot, but an anonymous, live embedding of the actual mind mapping service. Right at the first page, you get to start messing around with things. I think all Web 2.0 apps need to provide this kind of immediate use. We can provide such a low barrier to use, with no installation, but we've really lowered the bar, so to speak. The users won't jump very high for us these days. Let them trip and fall right into our arms.
I am just so excited about this. CARDIAC. The Cardboard Computer. How cool is that? This piece of history is amazing and better than that: it is extremely accessible. This fantastic design was built in 1969 by David Hagelbarger at Bell Labs to explain what computers were to those who would otherwise have no exposure to them. Miraculously, the CARDIAC (CARDboard Interactive Aid to Computation) was able to actually function as a slow and rudimentary computer. One of the most fascinating aspects of this gem is that at the time of its publication the scope it was able to demonstrate was actually useful in explaining what a computer was. Could you imagine trying to explain computers today with anything close to the CARDIAC? It had 100 memory locations and only ten instructions. The memory held signed 3-digit numbers (-999 through 999) and instructions could be encoded such that the first digit was the instruction and the second two digits were the address of memory to operat...
