I haven't found successful hubbers at HubPages to be snobby. Successful hubbers seem to either be willing to sincerely help less experienced Hubbers and point them in the right direction or stay pretty much invisible beyond their Hubbing activities. They just write, maintain, and collect their money. How do you define successful?
I'd put it this way. I started on HubPages nearly two years ago as a newbie, like everyone else who is just starting out, and never came across someone who thought a question was too stupid to ask or that sort of attitude. Sometimes Hubbers just pointed me eleswhere on HubPages for my answer rather than answering it directly. I imagine those who thought my questions weren't worth answering, didn't bother to answer, so I didn't catch any bad vibes from them. I'm sure others have had different experiences, but snobby Hubbers aren't going to keep many followers.
