Yes - I am happy with . . . .virtually all of my most recent hubs. I could definitely make them all longer - but I think that sometimes that is counter productive, as a web page reader tends to have a somewhat limited attention span.
I've got four and five thousand word hubs with all kinds of links, pictures, videos, and other stuff in them. . . .and they do NOT do nearly as well as hubs between 750 1500 words. Still though, some of my better ones are a bit more with the word count - but over 2500 words - I think folks are just wasting it. That's my experience though.
