Somewhere already there was a discussion about advertising on sites, and I will express myself a little about myself.
I usually find it normal when I see ads on a site with useful and / or interesting content. I am ready to watch it, because in this way, as it seemed to me, I support the owners of the site. The exception here is only one - I do not like animated ads. Beautiful flash movie, constantly annoying peripheral vision, immediately blocked with AdBlock.
Today I had to cut the banner and on Habré. Although, in general, to see a flash advertisement here was a surprise for me.
