I have had experience with this and am quite happy to see that mtwelve is real and not pulling any tricks, you do not have to donate although it is encouraged, I just want to give a shout out to a new service we all should embrace https://bitcointalk.org/index.php?topic=652076.msg7409146#msg7409146

Take 2 seconds to check out the site @ http://bitcoinist.net/

Hopefully new young startups with good innovation can utilize this to further exposure and get they're product out.

I will be watching for something new I can incorporate into activecoin.
