I am so, so sick of web sites that see I'm visiting from a phone and throw up a click-through notice that tells me they have an Android app available.
Look, maybe if you were the only web site on the entire internet that I visited then I'd use a dedicated app instead of a browser. As it stands it would be extremely, extremely over complicated for me to use a seperate app for each web site I visit.
I can kind of understand it for forums, but general magazine sites? What purpose would that serve? Just build a mobile page of you want, though that brings it's own problems if not done right.
