Editing Web Textarea with Desktop Editor

Nowadays we do a lot of text input on the Web, like posting on forums, filling out a support request form, commenting on someone's blog, etc. Although Web forms often offer a variety of so-called rich text editing capabilities, nothing beats the good old desktop editors. For a vim person, a plain Web textarea simply is not the place for text editing. Fortunately, for Firefox users, this pain can be eased. There are a few Firefox addons that allow people to use external editors for editing textarea. This wikipedia article lists quite a few options. I tried It's All Text!, and it works very well. It supports utf-8 encoding so I can write Chinese. Now I can seriously consider using gmail as my primary email client.
