Do you not think there are members here with a ton of rep and high post count who could know nothing about computers?
Oh yes. But if the ability to give rep in the social lounge was removed, that'd probably go a fair way to solving that issue.
I should re-iterate what I said in my first post - I don't look at member titles, rep, post count or whatever and assume "ah he must be knowledgeable." Whilst I'll be a bit suspicious of people with negative rep or a very high post count and very little rep, it doesn't go much further than that as far as I'm concerned, I'll judge each post individually on whether it's a helpful bit of advice or a load of misleading nonsense.
But I know there are people out there that do look at it this way, and for their benefit more than anyone else's I don't think the current system is as good as it could be in this regard.
I do agree with you about the Guru status though - if I'm honest this was really the thing that made me post. Senior member as a title doesn't necessarily imply knowledge, at least not that strongly. Guru however does - and the fact that someone can gain such a status through just posting lots in the social lounge, or posting lots of unhelpful advice elsewhere seems a bit misleading!
