Some (Probably Basic) YouTube Marketing Questions

Ok, so I use YouTube a lot and in bulk, but now
I want to focus on the quality of my submissions.
There are a couple of things I have run into and
I want to see if its taught/is the right thing to do
(i.e. for results, not moral/ethical etc).

1. Keyword "Stuffing"

I notice a lot of videos that get a decent amount
of views have long descriptions heavily loaded with
the keywords they have optimized for. Is this a
viable way of getting better results within both
YouTube and Google?

2. Inflating Your Views

I was paying particularly close to one submission I
saw this weekend. It was only a little while old and
had over 200 views. Now, the keywords were not
a great niche (home business/make money online
related) and they did use the long descriptions with
a lot of keywords, but I do not believe hundreds of
views were legitimate.

Is it a taught concept to inflate your views
artificially to attract views (i.e. the "what's the
crowd about" curiosity)?

Thanks
