When banner ads first started showing up, i was annoyed- but it was tolerable. Not everyone is willing to fork out the cash to maintain a webpage, after all. Unfortunately, due to the way the marketdroids defined "sucessful" advertising (that is: people drop what they're doing and visit that ad's site... sorry folks, you just aren't that interesting...) they weren't seeing much 'success. So then they started with the animated ads. That sort of pissed me off. It was damn hard to read stuff with crap flashing in the background, but it still wasn't too bad. But that wasn't enough for those bastards either, they wanted to disrupt you and force you to look at the shite they wanted you to look at, right now. Popups came around, and that really annoyed me. I grab a popup killer. Then came the flash ad. Specifically: the flashing red-and-white flash ad.
No more mister nice netizen. Ad blocking software with a well-defined block routine was loaded up. Now the morons are trying to get around my ad blocking software, which means i just get even better ad blocking software. Not to mention their language: attempting to say that because i'm not paying them/watching their ads that i'm the freeloader. No, i'm afraid it's the other way around: you're the freeloader. I have no obligation to pay you to use your site: you put it up on the net, and i can type your little adress into my browser, and up pops your site.
Now sure, sites like K5 or Slashdot get a ton and a half of traffic, so they probably wouldn't be able to exist without some sort of advertising revenue- but if people are going to try to force me to punch-the-monkey before i get into their site, i'll take my business elsewhere. I don't care if guys like that die off because i don't see their content either way.
The problem is this: the web was not designed for the way it is being used. There weren't supposed to be 5 sites that get 80% of all traffic (don't bother complaining about stats, i just made them up)- the web was supposed to be distributed.
