How often you find yourself in the situation you find this post on your friend’s wall, and you are curious and want to read or see more, but you actually do NOT want to add the application. What to do?
It is changing my behavior for sure, as I find myself clicking less and less on a link, because I know they want ALL my information first before I can see it, while often you can just read the article right on their own website, without leaving personal info (that is if you know the right address).
So be smart companies out there: make sure there is ALWAYS an alternative to your article before losing more potential clients / readers. And once the visitor is ready to add you, then they will, do not force them!
