Plurk has some nice add-ons that separates from Twitter. There’s an interactive timeline that shows threads and makes it easier to follow a conversation. There’s karma points for signing up people. You can create “cliques” to better organize friends. It doesn’t constantly crash (so far.)

Is this a business tool? Who the hell knows. I doubt the telephone appeared like a good business tool out of the gate. Is it fun to use? Definitely.

There are game-like features to it that make you want to invite more friends, post/plurk more often and get more involved. I’m not giving up my twitter account, dropping Facebook or giving up my blog for plurk, but like an 80′s arcade video game, I’m sure it’s going to get a few more of my quarters.

If you’d like an intelligent, detailed explanation of everything Plurk check out Frank Martin’s post on The Question of Plurk.
