I woke up thinking about why eivind's arguments on ad-filtering had stirred such a response from me. Well for those interested, it probably has to do with "not accepting guilt that is heaped upon me because I didn't fulfill someone else's flawed expectations". This is really nothing against eivind personally. In fact, I enjoy arguing ethics. For the record, the only thing like ad-filtering I use is "only accept cookies originating from same server." On the other hand, I think blanket ad-filtering is a great idea!
I do think that the current banner-ad-supported revenue model for many online sites is a temporary experiment that will probably fail for most, and eventually be abandoned as a valid model. I don't have a solution, but I would suspect that in the future, once the internet's novelty has worn off, sites that must directly generate revenue to survive will survive by subscription. (One idea for implementation would be for a site to offer a full-access time-limited trial subscription.) The content on such sites will have to be of high enough quality to sustain a large enough subscriber base. There are several I would subscibe to, including this one.
