David, first off: thanks for the nice words -- i love seeing the bike stuff moving here. there's a ton of stuff going on and it's exciting to see for sure.
as for the software, it's free and there are no ads and my buddy (alex) that hosts the servers in his basement already had this software on it, so we run this and the P2P blog on it. it's taken me some time to get used to and i find it a bit frustrating sometimes, but overall it's a great thing to have free/ad-free software that does what you want it to do.
i don't know of an icon secret decoder ring, though there is a big user community online if you were really bored...
