For the sake of the end-user and to satisfy curiousity of theirs, expand short urls provided by any service, be it Twitter, OCS or Status.net/Pump.io. http://longurl.org/api provides a universal API for doing so. Reproducible: Always Steps to Reproduce: 1. Open Choqok. 2. Look at post. 3. ??? 4. Get confused.
There's already a tooltip on anchor over, should be easy to replace text.
In the latest released code we introduced a new plugin for expanding URLs and it's using the longurl.org service, so this is fixed. More info: http://choqok.gnufolks.org/2015/01/choqok-1-5-released/
If you meant to REPLACE the shortURL with the longer one, then I should change this to WON'T FIX state! as we don't want to make the GUI ugly showing ridiculously long URLs.
