SO isn't SU - just cause they're all stackexchange sites dosen't make you a subject expert on all of them.
I have 70K here. Does that make me a great programmer? (Nope. I have 210 rep, mostly from correcting ONE typo). Does it make me a great parent? Does it have anything to do with my knowledge of pets? (well, I have 555 rep).
For that matter, does it have anything to do with my sysadmin chops?
In short, your SO rep dosen't count for anything here.
On the other hand, as a lower rep user there's always the option of suggested edits, so you arn't losing much. Its free rep.
I'd note I'm a moderator here, and I still need to flag things like a pleb, and often do suggested edits like anyone else of low rep elsewhere. :)
You'll just have to consider a good answer its own reward first.
