Web sites without advertisements in the middle of the body text still exist, such as wikipedia.org, tvtropes.org, and even slashdot.org once you've maxed your karma for a while.

I never see any of these spamvertisements that people are referring to, no matter what my karma or status is on this or that site.

Mostly that's because I use privoxy, which does 99% of the adblocking I ever want. However, I do on rare occasion play the "Block Content" or even "Edit Site Preferences" games in Opera. I think of "Block Content" as something of a first-person-shooter video game to shoot down intrusive spamverts.

I am so allergic to spamvertising of all sorts that I really can't read generic stuff on the web using somebody else's browser setup without going pretty completely batshit. I've been known to cover the stupid jumping pictures with giant postits or a taped on piece of paper. I am no more capable of reading static text while something is juggling screaming cats right in front of my face than I am capable of reading a book while a wailing banshee blasts out my eardrums from 2" away.

It's like how people with Tivo report that when they're visiting someone else's home and see a TV running with commercials on it, their first thought is something like "Huh! That TV's broken." That's exactly how I react when I come across someone else looking at the web with all its spammy in-your-face attention-seeking whinings: that their browser must be broken or something.

Disabling moving GIFs and sound by default is really mandatory, and really probably plugins, too, unless you have some other mechanism to block them. I've even been known to turn off javascript on specific sites just so the dumb things stop moving around on me. Even tooltip popup balloons can be maddening: just shut up, get out of my face and my mind, and let me read in peace, damn it! I would never read a book or magazine that had a loud screaming baby built right into it, and it simply astounds me that anyone puts up with this sort of outrageous assault.

I truly think that without the the serene freedom from the otherwise relentless spamvertising that this privoxy+opera combo gives me, I'd've long ago gone medieval and probably completely postal on these rude assholes. It's criminally abusive what they try to do to us.

Nobody has the right to strap you in a seat with your eyelids sewn open so they can steamshovel their spamverts into you. We call that assault, and nobody but nobody should put up with it. It's like the insulting "can't fast-forward through ads" property on some DVDs and some players. Their rights stop long before they reach my mind: I am not their prisoner, so go find some other sheep to bugger.

In a string context (in Perl, it would have to be something besides ===, but we'll get to that later), it would be "visually equal to" - any characters that are visually equal would be considered equal (useful mainly when using Unicode). So the Cyrillic "e" (0435) would be considered equal to Roman "e" (0065). I'm not sure how to handle complexities like "is the single character 'small a with macron' equal to the sequence 'small a' and 'combining diacritic macron'". We'll need a committee for that, probably. And since Perl uses different operators to determine context, we'd need something else for that. "veq", maybe?

You cannot use visual similarities between glyphs that may or may not look similar in one font or another, because there exists no standard that spells out their correspondence.

In contrast, there does exist a standard that says whether two code points should be considered the same basic character. This is what you get when you compare two strings at the primary collation strength using the Unicode Collation Algorithm. This is perfectly easy to do in Perl, and is extensible to locale tailoring as well.

To do more than that is to ask to translate 133t$p3@k into normal text. It may have some applications, but it is not as useful as you think.
