These work well enough for me to be comfortable with them:

• twittering-mode
• weblogger.el

Problems: twittering-mode doesn't give me a threaded display. That might be a lot of work. It takes care of OAuth issues, though. Weblogger.el doesn't post labels on blogger posts. That might be easy to fix.

I was just finishing up on some commits at work when I lost power. The UPS my DSL modem is on isn't working properly, so I couldn't push the commits to the server.

When I got home I realized I could've simply cloned the work repo, put a copy of it on my USB stick, and done a git push from my home box. Blah.
