I was just thinking a few days ago: Google is starting to resemble the last days of Altavista, where the results were full of junk.

If you use Firefox, some results that are full of a Firefox-specific scam where "you are the billionth search result" (maybe it also happens for other browsers). This has been going on for years now - I noticed it because scammers were scraping my blog for content and republishing it but making searches terms redirect to scam sites.
