Nevermind Google, keep an eye on FaceSpook
I'm more concerned that FaceSpook* seems to be taking an active role in manipulating story visibility. Many posts by my friends, a pretty progressive bunch, are pruned from view even when I specifically go to 'friends only' news feed and set it to sort chronologically. Similar story with pages and groups. This is the reason behind forcing all users to see what their flaky algorithms decide they should see, which includes significant amounts of advertising, and to hell with any preference the user has expressed. Then there was the crippling of the photo sharing feature (forcing handsets to download the jpeg then re-upload it with a post) when the Arab Spring was kicking off.
Seems to me FB is often effectively (deliberately?) a man-in-the-middle attack on people's everyday interaction and communication.
Their advertising algos need some tweaking too. No matter how many times FB put that grinning tory twat Goldsmith (for Mayor of London) next to promises to do the polar opposite of everything his lower-than-vermin party stand for, it will not influence me in any way. My membership of groups and pages with the strings "labour" and "green" and "corbyn" in their names should be enough of a clue. Anyone who wants to copy-paste The Sun Says at me will be ignored/mocked, depending on the effort made.
Pro tip: the 'FB Purity' browser extension is essential, even for casual users; FB is quite intolerable without it.
*Oh, feeling smug because you don't use it? Clever you, have a cookie. The fact remains it is a communications and news channel for millions.
Posting anon just because.
