Real Time Collaboration and Web 2.0 tools, tips, and reviews

Years ago, someone phoned you and you weren't home, you missed the call and they had to try back -- now, the messages queue up in voice-mail. TV shows used to slip unwatched by unless you were there to suck them up them in real-time -- today, my TiVo has hours of mindless crap that it's faithfully holding for me. The Web originally required me to actually go out and do something as quaint as visit sites to read them -- these days, my feed reader pulls down megabytes of data -- a large portion of it, of course, cat pictures -- and piles it up, forever. Each of these swollen reservoirs of data silently mocks me with my inadequacy.
