It doesn't bother me one way or another. I ignore things like scores, rankings, whatever, on here. I pretty much think most people who have been on this site for awhile don't pay much attention to the scores/ rankings, etc. of other Hubbers either.
It's also, however, not necessarily a matter of someone "having nothing better to do with their time". Many people who reach a certain amount of "achievement" on here have plenty of other things to do. They just happen to manage their time every effectively. For example, I have a family, a house (etc.), and I'm work from home as an offline freelance writer. Besides writing other material to be sold (completely different kind of writing than HubPages and similar sites), I'm fairly well along in establishing my own secondary business beyond my "main" one of freelance writing. I'll admit to not getting the chance to take many vacations, but I do have a social life (and now a daughter's wedding to plan) besides the work efforts.
Lots of times (if the project/time is right) I'll just leave a HubPages window up, and pop on and off to kind of take a break from the work I'm doing online (or at least on my computer). It can take three or five minutes every hour or two for the person who needs to take a break from something like reports. (Really... With some types of projects a person's going to take a little break anyway, whether or not she's got a HubPages window up.)
Other times, I may actually build a "day off" into my week for myself because I just need to have a day when I'm not "on duty". Sometimes, too, I may take the hour or two that someone else may use evenings to watch TV or talk on the phone, and instead write a Hub.
So, the issue isn't really who has no time or who has no time but finds a way to fit a bunch of different things into that time, Instead, it's more that most people on here don't feel "made to feel" anything because of stuff like rankings, levels, etc. Most don't pay a lot of attention to such things.
