Twitterfeed allows me to post to indenti.ca. I post all the tweets that I type in on my identi.ca account and have them forward to Twitter. As the status.net software is localised at translatewiki.net, it is easy to understand why status.net is my first choice.
Both Twitter and even more so Facebook want to determine what privacy and freedom I have and want to bombard me with things I have no interest in.
If everything works out well, Twitterfeed will generate a message to identi.ca. This will be forwarded to Twitter so in a way it is business as usual. When Twitter makes this impossible they will lose custom.
