I'm here from the main timeline. Plurk is superior over Twitter for the responses; it's easier to follow one conversation.

Non-tech friends might actually pick up Plurk more easily, since this "post and respond" thing is more familiar.

Also, what most of my non-tech friends are concerned about is privacy, so this whole clique thing is attractive to them. Ooh long response.

good reply though - they might pick it up quicker
