We also had (still have) an account in Xanga.com that was part of our first steps in the blogging arena and we kind of agree with Singopolyma, that wasn't a place to stay, we even had, prior to this unused account, x-journal, that closed down a while now. We loved the last part of his post and under Creative Commons atribuition, we reproduce the last two paragraphs of Singopolyma's Microblogging: The open Wall
"Now think of microblogging. Think of how you use it. Yes, there's a publication aspect to it for sure (I say what I want people to hear). There is also, however, this element of public conversation people seem so interested in. Back-and-forth between two or more people, on their own pages, archived publicly.
What's even better about this realization? I hated the Xanga comments, I hate the Facebook wall (and their new 'comment on status' feature), but I love @replies. So it wasn't the concept of public conversations I wasn't getting, but merely an implementation detail. @replies are piped through a good notification system (which for Twitter these days involved scraping a feed and re-posting it to a fake identi.ca account so that I can get them via IM) so that they can be near-real-time when I have time, and are still there for me if I don't."
Thanks to Stephen Paul Weber, an expert on Web development, Desktop scripting, Linux, FLOSS, Creative Commons, and reading we've discovered the identi.ca and the good use @ replies in Twitter.
