Network will not grow without a pool...
Yeah think there is challenge with creating pool, also need GPU miner. Don't think anyone is working on either.
I would be very very interested in a GPU miner!
And I could organise some good GPU mining power with guys I know, to push Zettel, if the dev wishes that.
i think the dev said he/she wanted to extend cpu mining as long as possible. I'm still finding plenty of blocks on a few processors. difficulty dipped down to .75 but back up to about 1.0, but still not up to the 1.6 it was a week or so ago.
the dev answers questions every other day or so...probably won't be long before we get more discussion.
