Poll results; new poll

Just 16% of poll respondents features non-Adsense advertising on their sites; this number seems low to me, though it leaves me with another question that was not asked: why?

So, if you're one of the 40 people that responded 'No,' I ask you: why is it that you don't? Is it from a lack of interest on your part, a lack of interest on the part of potential advertisers, or a combination of the two? Personally speaking, I feature (minimal) advertising on both of my sites, and I believe all of it has been initiated by the advertiser; I'm content to wait for offers to come in - if I like them and their product, great; if not, no sweat off my back.

New poll concerns the LAMB Scroll Box. I'm curious - with it containing just short of400 LAMBs, do you think it serves a purpose still? Though I use it occasionally, I can't say that I use it to do my browsing - I use a feed reader for that. And though it might be great to spread link love to all of the sites contained within it, I've also heard that it's possible that its existence hurts the page ranking of sites that feature it (something to do with links within Javascript and the way Google interprets them). So I ask you - has it run its course or do you find that its held its value?
