And so I finally got on...
I honestly tried to approach this with an open mind considering how I think Windows Live is quite tolerable, Win7 enjoyable and Office 2010 bearable (I also kinda enjoy it but heck).
SO... Its a search engine. Okee...
I search for "Anime" and get several hits I'm not interested in. Ok, so I search for 'Ableton' which is the name of a software company as well as DAW environment. Only to have some nitwit 'tag' my search result as "Windows 8". WTF?
So now there sits a "feed" somewhere which I apparently made; it says "Ableton", it lists some screenshots and other stuff and because it tagged "Windows 8" it also lists a whole lot of Windows 8 crapola.
And of course; one can only "like" things, can cannot "dislike" or "no" vote stuff. Wonderful...
So I eventually find the option to edit my "post" (WTF?!) and remove a tag. Only to get greeted by some weird error message.
And so I eventually managed to remove the entire "post" (what post, I was only trying to use a search engine ?).
Only to have that pesky person all of sudden follow me. Yeah right; I bet to tag more serious stuff I look for as "windows 8".
RIGHT, so that's my experience so far.
And it leaves me wondering: Why the HECK would I want to use this utter and total display of CHAOS instead of my trusty search bar in the browser which gets me to Google or Bing ?
Who cares that when person A searches for item "B" several people might find the time to immediately "like" it and "tag" it. What good does this do ME ?
AND why can't I rant like this on a social network? On Live I can put "Looking at so.cl, WHAT A MESS!" in my status.
As such my conclusion: FAIL!
