METANAUT  Great app, but two things I hope get addressed:

1. The "size" of the application, the space it takes. If it were smaller, more resembling Twitterific or iChat's Contact list, I think it would be more in line with the "status" windows in other applications.

2. The icon. Normally not a big deal that it's so "unfinished" looking, but since it's reporting information in the dock, some refinement on par with other apps would be nice.

If it fit better with the baseline quality found in other apps, I'd probably use it more.
