Ragnor: Unfortunately when publishing on the public internet you have no control over how your content it consumed by end users.
I subscribed to support the site because Geekzone is awesome, but I used to block ads that were annoying and generally block ads on many sites.
Personally I don't think using a browser plugin like AdBlock+ is morally any different to throwing out the junk flyer in the middle of the free local suburban newspaper or skipping ads in recorded tv, that's life.
Alternative models to ad supported content will naturally emerge to counter the ease and increase in ad blocking online and ad skipping in media. Tech Dirt has some great articles on connecting with fans and giving them reasons to buy.
I do however think blanket ad blocking for your network via a proxy/router/server is a mistake, this should be done at the browser level so it can be turned on/off selectively not at the network level.
The Times in London went behind a paywall completely. The sub is expensive comparatively (especially outside the UK because the better value packages are not available outside the UK) but I have not regretted a bean of my sub.
No ads, journalism that makes Stuff and the Herald look like junior school project papers and of course that bastion of civilised life, the Times Crossword.
