There are 3 or 4 Twitter accounts that I follow via browser just for entertainment purposes. One in particular I find particularly entertaining because his sick sense of humor is so much like mine.
For a few months now, there has appeared a popup dialog on opening of the web page of each offering the opportunity to Log In or Sign Up. A little annoying but it always had a convenient X to dismiss the dialog & go on about surfing.
That was until today. Now the dialog cannot be dismissed and surfing the tweets is verboten. Sign Up or Log In, that's that.
Their product, their rules, but doesn't really make me want to Sign Up much. Eff 'em.
