Just got an invite for Yahoo! Meme. Here is my profile! (Let me know if you want an invite.) Not sure what I really have to say that would be all that different from what I'm already saying here and my other blog.
In addition to that, I also manage Twitter, Plurk and Facbook accounts. I've really de-prioritized Multiply since people only seem to do re-posts there. Also haven't been taking that many pictures, and that was really the point of that site, at least for me.
And now there are so many more "lifestream" sites and I just don't know what to do with my Posterous, Tumblr... Not to mention the social bookmarking sites, playlist sites, scrapbooking sites, professional social networking sites...
Anybody else encountering the same problems?
