after all it is their business, I just do it for fun.
There you go again.
You seem to be mistaking this site and forum for some big company instead of a group of enthusiasts who have chosen to cover their expenses by offering products through a webshop and other (commercial) channels.
You also seem to expect some team of professionals to full time guard the forum and all other parts of this site.
I've seen some remarks of users that seem to have such expectations.
To be able to do so, Arduino would be twice the price it is already, if not worse.
Keep in mind that this Arduino stuff is about hobbyists, from and for hobbyists.
Someone who expects professional support, should choose a professional platform, with professional consequences.
Having said that, there's lots of things that can (and/or should be) improved.
Anybody pointing that out is absolutely right.
At least some feedback on requests and remarks would be nice.
