Are web 2.0 to-do lists just hype?
pedalpete: I don't use any web-based todo list, but have tried a few more for curiosity than as a solution to a problem.I think the reason so many of these things exist is
1) the functionality seems fairly simple
2) the market opportunity is hugeWhere I think most of them fail is that they don't (as far as I have seen) provide a compelling differentiator or improvement over pen & paper or txt file.Sure they are easy to use, but so are the alternatives. 
Is there a killer feature that is making a to do list better than a txt file?
If so, i haven't seen it.
