People generally say the ideal or using your own word decent CTR is 2%. But it is better to have a CTR of 5%. That is considered as good one, especially when your page views are less. Less number of ads, better placement of ads and suitable blending all will help to increase the CTR.
that entirely depends on your niche. some niche will not even give you 2% CTR no matter much much you try. and some niche might give you 10, 20, or even 30% CTR. again, entirely depends on niche and ad placement/blending in

Niche determines Ctr alot. celebrity sites have low ctr same with forums. Specific topics can get very high ctr
Yes Forum have low CTRs... I am getting about 2.97% CTR from a blog Adsense with search via Google Coop is also not too bad; I'm getting about 5% on that
CTR depends on the niche. I have sites that get 1-2% as well as sites that consistently get around 30%. Overall my average for all sites is right around 8-9%
Its not a constant thing.. may be 2% is ok with some publishers and may be 10% is not sufficient for some.
