I just thought I would post a quick note to “big-up” a site that I have been using today (and collegues for a while) that really rocks my boat in terms of Web 2.0 being useful.
Basically Voo2Do is a task management tool in the same sort of vein as ta-da et al. I won't go into details about how it works and what you can do as thats all on the site, but I can wholeheartedly recommend signing up and trying out.
…and before you ask, No, I'm not being prompted to say this, I'm doing it off my own back…
