OB Ads?

I have not accepted any compensation for anything I’ve done on this blog.  But folks keep offering to pay me to put their ads on this blog.  I wonder: am I being too prudish?  Presumably the more money I make blogging, the more I’ll blog.

So let me ask you all:  how many readers would think less of me or my writings if had a special Ads sidebar, but promised that ads would not influence what I blogged?  How selective should I be; am I implicitly “endorsing” the advertised products?  And how much should I charge?
