I found it too stressful to try to keep up with it, the AOTM guesses/selections, new releases, other stuff I wanted to check out, so I had to stop following, unfortunately.
Yeah, once a week was too much for me, and tbh, if it was really far out of my wheelhouse I didn't really give them a chance more than one (or less) listen. There's just too much music. I've decided its ok to not know everything, lol.
I think weekly is ok because there are probably a lot of people to get through. I think the difficulty is in the discussion. It would be cool if there were ways to vote on if you liked it...or had some type of poll about what stood out...I find the hardest part is dedicating the time to write something meaningful...but I still listen to everything that's posted or at least add it to the listening list.
Another idea would be to pair picks and let the group compare them (via poll, like or discussion) over a two week period..working towards what the best pick of the month was.
