As relache has said, I don't compete with other Hubbers either. What other people do or don't do on here is of no consequence to me with regard to how well I do. There's really no need to compete with other Hubbers, because everyone's collection of Hubs is as individual as each of the thousands of Hubbers.
Two people could write equally good Hubs about the very same thing, both of them could even end up on a Google-search page 1; and the success of each of those Hubs and Hubbers would still depend on other things that Hubbers, themselves, did in terms of writing quality and traffic. Besides, one of those Hubber could have written 100 other successful Hubs while the other may have written only 5.
As relache said as well, I only "compete" with myself.
