Kulga I'm suddenly noticing the forum feels a bit more "busy" with the post controls constantly visible
I'm starting to notice that too ... as you say, especially when there are a lot of short posts in succession.
I'm going to wait a while and get acclimated before deciding whether it bugs me. Probably it'll get filtered out.
EDIT:
Just to bring up another possibility, though ... how about using icons for "Like" and "Reply" as well?
They'd take up less space that way (good for mobile?) and making them graphical rather than linguistic might help cut down on the sense of busy-ness. Just a passing thought. (It'd be a good idea to add tooltips for all three buttons if you end up going the icons route.)
