I was pretty excited about it 3-4 years ago, but it seems like it's kind of an abandoned project at this point. Anyone making use of it and have any impressions?

Development is pretty active, and the latest release just improved the routing algorithm by having it favour hops with the lowest latency which had a noticeable improvement.
If you're looking for a big community hub within the network you might be disappointed (you could always try to set one up!), but there are a lot of people using it for their own purposes and the protect is far from abandoned.
