I disagree with you - but I'm not downvoting you because I think you bring up an interesting point. The problem, though, is the advertising on buy.com, monoprice.com, amazon.com and even google.com is actually quite useful for me. Sometimes even the ads on dpreview.com are interesting. The issue here is intent - on these sites, I am looking to buy products, product reviews, or (in the case of google) searching for something that might be product related.
On my social networks (Path) - my intent is to see what my niece is up to, what my friends are doing, and what my mother's latest project is.
It is not (and never has been) to "Find a Female Friend in Redwood City", or, "Check out the Kmart Special".
It is this disconnect between intent and ad-presentation that makes the pollution of the twitter feed so offensive.
