The article was already posted to HN by someone a day ago. It can not be posted again unless its URL changes.

As a long time user of HN, let me offer a couple of suggestions:

(1) Change the title o the blog article to be more descriptive; on HN the title of your submission should match the title of the original blog article. Things that look too much like PR or shilling (avoid using words like "brilliant") will very quickly get an article flagged.

(2) The best time to submit something on HN is 7-9AM PST on a work day.

(3) HN has a very sophisticated user base. Don't just submit the article and walk away. You need to be able to inteligently answer (at times very pointed) posts in the comments.

(4) HN has very good defenses against astroturfing. I wouldn't try to game the system.

There's no way to lock out gpus completely, the only possibility is making it as hard as possible for them.
PTS and MMC are doing pretty good there, with a maximum of 10x more speed. Have a look at what the difference is for other coins and you will see that's a huge improvement.

It only took 3 weeks for a GPU miner to be released for MMC that has a hashing rate an order of magnitude greater than what is possible with CPU mining. Compare to Primecoin (and Datacoin et al) where after 1/2 year and much greater economic incentives, attempts at producing a GPU miner haven't amounted to much of anything (someone released one, but it was not faster than CPU mining; nobody uses it).

I'm sorry for being negative in this post, but as news about MemoryCoin 2.0 spreads through the larger crypto-currency community there are going to be a lot of people who will be more critical than those in this forum. We need to be prepared for that -- the best way to prepare is to honestly assess the strengths and weakness of MMC.
