If you need more than 140 characters to express your feeling at twitter, you can try this service, TwitBlogs. Basically it keeps the post on their homepage and post the title with a short link on your Twitter profile. It is like having your own blog (but this is using their blog services) with the use of Twitfeed.
Here is how it looks like on my test post to my twitter account.

Try TwitBlogs





It looks cool. Is it your post title is a long “sad”?
Nice info. It looks cool, I’ll give it a try.
Oh great. This wil be much useful to me.
Isn’t the whole idea of twitter that you only use 140 characters? Its a good idea, but chances are the majority of people reading your twitter post won’t follow an external link…
