Anita the threaded conversations are the big advantage that Plurk has over Twitter, IMO

Not sure yet. Will try to revist your question in a week or so.

I'm with Mack, although I'm hardly a Plurk expert or power user.

One2one conversation is much better on Plurk, you can start "cliques", etc.!

Thanks a lot for friending me on Plurk, Anita

Well... Its been a few weeks and the only plus I have found is that it is a bit easier to reply to old posts such as this one.

plurk is more geared to discussions which is better than twitters collection of oneliners.
