That bit of popping up something about joining or subscribing?
It blocks the content I was interested in!
Do you know what that does?
A) Make me wish to join or subscribe?
B) Make me consider joining or subscribing?
C) Make me look at/for another site instead.
D) Make me irritated at being delayed and LESS likely to join/subscribe?
E) Make me want to trample the idiot designer to paste?
F) C, and also D and E.
Think about it a moment.
Got your answer?
The correct answer is: F.
Those who comprehend F get an “A.” Those who expect A get and deserve an “F.”
Yes, it’s so annoying I have ZERO interest in joining up with the idiots who prevented the accessing of the information I sought. And yes, so annoying my normally fairly easygoing self entertains ideas of crushing said idiots underhoof. Want me to subscribe? Put a much more subtle button off to the side and sell me on the content. If you must interrupt and scream, you are admitting even you consider your content insufficient. That’s why C. Unless your site is truly unique (unlikely – yes, really), chances are someone less annoying is doing it better. They (and their advertisers) get the traffic. You (and your advertisers) do NOT.
I know this won’t change anything, alas, but now I’ve said it. Those who commit this stupidity wouldn’t be “first up against the wall when the revolution comes” (that’s the auto-play assholes) but they’re pretty far up on the list. Even before the “Listen carefully, our options have changed” liars. And yeah, you know those jerks aren’t far down the list at all.
