Mustard (software)
Mustard is a microblogging software application for Android, compatible with both Twitter and Status.net services.
As of February 28, 2011 it was the most used identi.ca client for Android platform and the 14th most used client overall.
It is mainly developed by Michele Azzolari and one of the most interesting features is the ability to consolidate different timelines from different accounts into a single list. On the missing features list, the ability to send "direct messages" to individual users without appearing in the public timeline.
