Pownce is best, but it is too unactive, twitter is too unstable and replying is annoying, plurk is weird, identi.ca is even weirder. So I think best micro-blog is kwippy, or Pownce. - k00pa

Twitter. Don't forget to check out http://youare.com/islamcrunch - Mikael Pittam from twhirl

Hmm for real convosations it must be plurk for sharing pownce for alerting something new twitter identi.ca just open freaks kwippy for fun.. I would say plurk for mirco BLOGing. - JegerPhil - Phil

I hate Twitter & Plurk & Identi.ca. Pownce is ok but I think Kwippy is best. - ChaCha Fance

what about jaiku ? It didn't make the list... - yvons

Pownce probably is the best but Twitter still has a much larger user base, Plurk is childish and identi.ca has nothing different other than login with OpenID. I'm still trying out Kwippy - João Almeida from twhirl

Twitter, Plurk, Kwippy is also cool - Hisham Sadek هشام

I wish Pownce was big as Twitter, that would make it the best. But I'm commenting on FriendFeed. Go figure. - phil baumann

I'm begining to think of Disqus as a micro blogging format. it does have a linear quality as well. and it takes in Seesmic which I like - Noah David Simon

Jaiku and youare are not on list, because I forgot that them also exist. - k00pa

I am a Jaiku fan: best of all these worlds. Too bad Google killed it... ;( - Barbara K. Baker

Hi k00pa, we are introducing YouAre and we are proud if you could test our service. More info: http://friendfeed.com/rooms... - José Luis Antúnez

Twitter for rate of growth (but not for quality), Pownce for quality but not mass. I'm not big on Plurk, but I'm trying out Kwippy this week and like the idea so far. - Garza

Twitter for ease-of-use, simple GUI, first to market. - Rebecca Povio

the new Gtalk with open social is going to be kewl - paisley

Plurk, not perfect but great GUI and more addictive than the rest - Kol Tregaskes from twhirl

I'm still missing the point on Kwipp, it looks like just another Twitter clone, at least Plurk has a different twist on it - João Almeida

I think friendfeed is best for both microblogging and conversations - Svartling

is this link, comment baiting, what... do you really WANT to know or do you just want to get a lot of worked up replies? Cause if you REALLY want to know, ping me and I'll tell you. - John McElhenney 2.0

@JMac by suggesting you have THE answer, you kinda missed the point. - Brian Carter
