They're all mostly the same until tested - bunch of hooks into the
registry for watching, selling your habits as information, the hustle
of coming back with direct advertising, all kinds of bullshit spam
suddenly showing up from nobody you thought you knew until installing
it. Total kludge like sugar into a gas tank. Very good for everybody
is it's something for nothing. I keep binary images for that purpose,
give out in like kind bullshit information when possible, and use a
system restore like washing my hands of it afterwards. The good stuff
is out there, just takes a little looking.
