Been playing some more with Yahoo Myweb &c. (they need a new name, like, now). Coolest new thing so far is ability to import bookmarks from “RSS feeds” (read, del.icio.us). I managed to get the xml file from the del.icio.us API to look enough like a well formed RSS file (thank you Textpad) for Yahoo to accept it. Now, other than having a complete backup of my bookmarks — sans descriptions, Myweb doesn’t yet import them properly — I can’t really see what else to do with it. The community thing is being touted highly, but so far, and I hate to say it, but whoop-te-do.
Update: 360 is not going to remain the default relationship management tool for myweb, apprently. And Myweb is proving to be a lot cooler and more addictive than I ascertained at first glance. So forget I said all that.
