1) Everyone wanted to blog, nobody took the time to read everyone's blogs, few invested the time to write blogs. 2) Absolutely. I would argue that most gigantic successes come out of having an inkling of what people want vs. being the outcome of a gigantic time R&D investment. 3) Simplicity - and this is the same reason that Wave didn't. If people are able to go from "I have no idea what this is" to "I know how to use this" in a weekend, as Leo Laporte often talks about, it won't die on the vine. You can go from rookie to I'm able to use this (note: this is different than "I get why I want to use this") on Twitter in under an hour - and enabling people's ADD is the best way to traction.
