You need only twitter auth.

Let's assume you don't want to remember anything. But once when you do a commit you might do it like:

git commit -m "Add magic beans to make super scale //tweet"

Is it easy enough?

Most services are useless for most people. It's true. I built it because I need it myself. But I can assume there some people just like me in the world.

Not sure, they have enough flexibility. But I ll try anyway

It's pretty hard to get formatting you need with rss feed. In some cases formatting human readable tweet require addition GET query to github API and many other more specific problems.

dlvr.it is just to general to be good for one thing. tweethub is good for one thing.

Well, in this case you might like the idea to share individual activities, not all of them.

Because it's needs * serious formatting * no options what to share * no share individual activity.

I tried twitterfeed on my own and All reasons above makes this approach not really good.

More options exists. Unfortunately I didn't mention all of them in screenshot.
