Yenten looks like a small coin. Its market cap is currently 217k. I don't think it's considered proven. But I don't mind supporting a hard fork with Yespower, like BitflateYes, if there's enough community support. I prefer hard-forking the blockchain to benefit existing coin holders.
Another thing that coins do including bigger coins like Myraid ($15m) is include Yespower as a proof of work option among other options. This allows people with multiple types of hardware to mine, however the downside is each certain algorithm splits the pie so miners of a certain algorithm won't necessarily profit as much on a coin that supports multiple algorithms.
I am a supporter of the idea of BitflateYes fork, if that is what you want to do. Also just a hardfork without a split in the chain will also work to benefit current coin holders, and people would just switch mining Yespower for the future for Bitflate, there aren't many sha-256 miners on Bitflate anyways.
