I wonder if there is so much solo miners?
Yes.
Example I do not want solo mine (and also not know exactly how to do it) with my poor average 2.8kh/s hash power (only this amount I can use for YAC because my R9 280x rigs really are not at all for N16 (they can but N16 is really not for these radeons)
How can find p2p nodes? In YAC coin information side and here page one many links are obsolete.
It is not good for coin in long run if it is some kind of "insiders club". Informatrion need be updated.
Setting up solo mining is not particularly difficult. Getting the actual miner up and running is the hard part, and you've already got that covered. If you're running the YAC wallet too, then you're 95% of the way there. With 2.8kh/s, there's not much reason to be afraid of solo mining. Pools are useful when your hash rate is low enough that you'll rarely mine a block on your own or can't take the risk of a long dry spell due to variability, but at 2.8kh/s and the current difficulty of 0.0012, you're likely to average about 30 minutes per block found.
After the last N change, I cranked back up quite a few otherwise-idle blade servers CPU mining YAC to keep things moving along after a lot of GPU miners stopped mining and to shift the balance of hash rate away from certain pools having too large a share of the overall hash rate. So, at least some portion of the apparently large non-pool hash rate is me solo mining at the moment. Thirtybird is probably another good chunk of it. Granted, I'm mining at a loss (in terms of power cost), but I'll probably leave it going for the winter for a little extra heat in the building the servers live in.
