The decline of the Internet

I've just been searching the internet for information regarding the source of bubbles coming into my pool from the filter return lines.  Not that it's a big deal, at least I don't think so but I wanted to see.  BTW, the pool is now up to 80F and just wonderful, shorty (grandson) won't let me go a day without a swim and I feel like the summer fitness program is well under way.  Great way to get a good night's sleep after a swim.

But anyway, back to the bubbles an internet search yields what seems like a lot of useful results.  But on closer inspection, they are a lot of duplicates and the sites are simply aggregators.  I mean like: Ask.com, Instructables, Wiki answers, Wikihow, Ehow, Homegardenguides.com, and Yelp.  Ehow is my least favorite, the article is a bunch of generalities (did you know that air in the pipes can cause bubbles?) surrounded by ads and links to other marginally useful articles.  Although the link to a pool demolition company may be the ultimate solution.  (I did not appreciate the redirect through an ad site to get there.)

I thought our friends at google had made changes to lower the page rank or aggregators, at least there was some fuss about it a year or so ago.  But they seem to be going strong.  How about a search that then removes duplicate articles?  I'll take $10 Billion please.
