Just a bit of honest feedback.
I actually thought wikireef must have been dropped. It was only when I saw this poll that I went hunting for it and found it under the dreaded "more" option. I say that semi tongue in cheek as I'm one of the many who are blind to "more" options, I simply don't notice them.
This all reminded me - although it was 15 years ago. When we were developing our online market presence (for a division of the number 2 soft drink company in the world) we hired a prestigious research firm. Surveys, focus groups and blind live trials against control groups demonstrated a number of trends & a there were a couple of things that stick in my head because they described me too.
The total sample of people was 200 from a broad demographic, excluding the then elderly. I pass this on in case its helpful.
More than 7 tabs was too confusing and resulted in losing the users' attention, frames were very disliked, & "more/misc/other" options were largely viewed as places where the unimportant stuff is put.
I grant you this was 1999 and perhaps users have matured in their habits now. Then again it may just be the human psych. Anyway now that I've found wiki, I'm off to have a look.
