@mrkrndvs @vishae I do kind of like to use 'em all don't I? I think I've even created some additional ones along the way. I suppose the key is to have a good use for them and use them regularly. I also tend to do a lot of self-site searching, so having them delineated well helps in that.

I do however, highly recommend using bookmarklets or other micropub methods to make the data collection easier, otherwise, as @matigo mentioned, you're killing an awful lot of time.
