When you get used to a text editor that you like, you start to get annoyed by all the times you have to enter some text and you're using a shitty editor. This is so true on the web when you try to write something in more than 140 characters.

Matthias showed me a nice firefox extension: “it's all text” (you can also install it from debian repos). For each text box, you just click a small “edit” button and it will fire up vim[^1] and let you edit the text there, then send it back to the web interface.

[^1]: Actually, I had to configure it to start GVim instead of vim. I suppose there's a way to launch a terminal and then vim…
