OCRAM  Excellent application, nice, small, simple, stable. Just two remarks:

1. I'd also love to see ping.fm integration, that would be really really great

2. I can't set the hotkey, can I? It would be good to make this customizable.

Thanks for the good work!

TEXINICK  Hi, just a small suggestion... could you add in the ability to send the message to Ping.fm? This would then make your program an attractive option for people who use the majority of the social networking sites. i.e. Ping.fm (I'm not affiliated) can send messages to Plurk, Twitter, Facebook, etc etc etc, (there are loads).

JP4SOFT  This is exactly the kind of twitter client I was looking for. The screenshot contains disabled checkbox for posting messages to Facebook. I hope this functionality will come soon. I like this easy way of publishing as I'm usually too lazy to open some special application just only for posting what I'm doing. This app allows me to use twitter much more frequently.

KITER  Nice simple application... You don't need to have any open twitter client for posting to twitter. Just only press command+option+P and type what are you doing.
