Blinking ads
It is becoming extraordinarily difficult to concentrate on anything, because of all the blinking ads.
I know of course the site receives precious revenue from the the advertisers, that goes without saying, however I am getting a headache every time I log in.
This is such an issue for me that is it affecting my decision to come in to the site, or not.
Solutions:
1 . No blinking ads.
2 . Enable ad free site for a nominal fee. I would be willing to pay $5-10 / year for this privilege.
