I am really really interested in picking this game up, but is the community active enough for it to still be worth it? I imagine that it's not nearly as fun with no one playing with you.

The GB server is the most populated one in the US with about 15-30 people on during peak hours but there are a few European servers that have high populations too.

Also, It's trackmainia! There is always activity. It's like Counter-strike of racing.

You can always find servers to play on, just a few, but still there's a relatively active community. I think it'll have ups and downs as shootmania gets closer to release, but I think it'll still have that central group! Pleeeease get TM2. Shit's dope.

when are peak hours, i usually get on it after work 7pm EST and there is barely anyone there; though it does pick up at 11pm.

I rarely see activity on the Giant Bomb server because of my time zone, but there is always german servers with 50-70 players at a time when I am on.

played just after i posted that, at there were about 30 players on or so, but it emptied; i guess i play just in time for everyone to get tired to playing.
