I have seen many blogs which makes good money via adsense . labnol.org , technospot.net and few more are their in my tracking list .
You guys are definitely thinking big. My blog has been running for a little over a year, and despite pulling in ~1.5k UV's/month (not a lot, I know, but I'm looking to break 2k - maybe 2.5k - this month, so its going in the right direction), and I've not even made $100 total I'd love to make more, but I'm not going to spend my life stressing over it. Keep making your blog the best it can be, put up the best content you can, and eventually the traffic and the revenue will come (at least thats what I keep telling myself)
