But that's only meaningful if you followed the link in the first place. Sure it can be useful to be told in advance "Oh, by the way, the page I'm recommending is in Turkish", on the off chance that the link text itself doesn't give a clue. ("This page in Italian" or "My favoritte smileys site defaults to German though you can change it if you're a wimp", say.)
But it's far more important to get information from the page in isolation, the way you'd get it if you typed the address manually or used a bookmark or, heck, came in from a search engine.
Now, if you wanted to mess with a competitor by including some perfectly legitimate links to their site, and coding it to say the page is in some obscure language so it will come up in the wrong searches or the page title comes out meaning something vulgar ...
