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 think the reason Myraid gets lots of miners is it is merge mined in addition to 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 to mining Yespower for the future for Bitflate, there aren't many sha-256 miners on Bitflate anyways.
"yespower in particular is designed to be CPU-friendly, GPU-unfriendly, and FPGA/ASIC-neutral. In other words, it's meant to be relatively efficient to compute on current CPUs and relatively inefficient on current GPUs. Unfortunately, being GPU-unfriendly also means that eventual FPGA and ASIC implementations will only compete with CPUs, and at least ASICs will win over the CPUs"

I found this quote in Yespower FAQ. Yespower isn't truly ASIC resistant. Eventually, ASIC will replace CPU mining for Yespower.
