Well they keep breaking main FB page with additions or redesigns nobody asked for.

I am in Europe but I must be some test bunny that made some personal enemy there somehow, since beginning (cca 2008) FB was by far the buggiest site ever. Uploads of images didn't work, sometimes it uploaded twice. Uploading album of 30-50 pics took on average maybe 10 attempts in the past. Comments didn't work, or twice again. many similar behaviors. Ie since cca 2 weeks now if I click on some picture to have it full screen, clicking close after 1-2 mins ends up in FB error page instead of returning to main feed. I keep seeing FB error page a LOT considering infrequent use.

Horrible, terrible engineering.
