I check in on a few, but the ones I watch out for regularly are:
Autres Directions In Music for soft indietronic weepy lameness. Haha. Ok, not quite. Walking to work this morning I was listening to the release by Obadia (for the nth time) which is sorta weirdo difficult stop-start trip-hop or something. Loud hip-hop beats, vocal snippets and hyper edited acoustic guitar.
Monohm for crackly minimal stuff along the lines of SND and Pole and whatever.
Filtro for more mellow 'n' minimal electronics. The first release was outstanding (if a bit exhausting - a whole lot of remixes of one track), but I have to admit I haven't got so excited about other things I've heard from there.
I've tried to find more, well,
fun music out there, but there's really not that much that stacks up, IMO. I've heard a few tunes I liked via
Disciples of Ageema Blues, eg. Julien Love's 'Waterfall' - fun sorta Arthur Russell-y thing.
