Thank you for the article interesting information but …
I don’t think that in the table you show actual statuses of projects. Specially tried to test Tenx and Monaco.
TenX — error on sign up from mobile app, looks that it’s still in testing stage or some alpha, but I can’t to sign up.
You are right about experienced feedback from mature designers, but usually you will see only “Awesome”, “Cool” at Dribble and will not get a real feedback, because everyone trying to be kindly. Probably only your friends will be able to give you honest feedback.
Yes, I understand what you mean, but like I said versions we used cover most of cases and I don’t like to have a lot of useless tags at the head of the site. Also it’s affect on page load and amount of requests, for example if you have 16x16 and 32x32 icons(like realfavicongenerator recommend) browser will load both even he can resize to 16x16 from 32x32 versions.
