I must admit, I've completely forgotten what Internet advertising looks like. I installed Adblock Plus with Firefox a year or so ago and I haven't seen an ad since.
Not a single one.
If you have yet to declare your independence from ads, I'd encourage you to do so. It's strangely serene browsing the web without advertisements.
It's not immoral to browse ad-free, as some suggest. No, there are than simply spraying ad graffiti over everything. Entrepreneurs might just have to think again - use a little creativity - to figure them out.
In the meantime, I just wish there were a way to take Adblock Plus offline....
