Just this morning I was thinking of making a search engine that only looks among personal blogs plus a whitelist of sites like stackoverflow and Wikipedia. Or something like the old web in general. Or it has to be non profit (no ads, no subscription options, no paid content, only donation/flattr if anything). I haven't decided on a good rule yet, it's quite tricky.
At any rate, the idea is to somehow filter out all the garbage when I just want to know how to do something. Too often I have to find personal blog links on stackoverflow ("PS. I wrote more about it here") as opposed to that helpful article simply showing up in the search results by itself.
