YT & TAGS - what is your opinion

Seriously....I've read on a @*&^% ton of forums, ebooks and whatnots about tags...

Most of the time the info I read is that it is best to fill up the tags to the max

HOWEVER - I see videos with like 4-5 tags with over 1 milion views and virtually NO DESCRIPTION.

The TAG TO THE MAX concept seems to be somewhat off (I THINK?)

I would like to know what you think

I imagine in certain context it would be best to have less and others more?

Nobody has any opinions on this?

When ever I add tags I the first one is what most people would search for on YouTube. For example; Minecraft, my first tag would be Minecraft then minecraft, mine craft, Mine Craft. I always do my tagging this way then I add in the tags that my keyword search tool scraps. Best of luck.
