Pros: Mods can see spam posts quicker
Experienced users can see new posts easier (I.E. you might have 4 new posts in the Hardware section at once, but only shows as 1)
Cons: Too much information on the page? (more directed at newbs)
Hows compatibility with Mobile browsers?
I personally like it, does it automatically update, or do you have to refresh the page? Maybe auto settings starts it with the arrow / tab set in (so you cant see it) Does that then defeat the object? My views anyway
