I tried to read seeking alpha on mobile Safari. I was not logged in (first time user). I got an interstitial advertising the iPhone app every time I loaded a page. There was no visible way to get away from the interstitial. So, I couldn’t read the site. I didn’t want to download an unknown app. I almost gave up but then found the membership page and was able to create an account.
Tl;dr: if you want new users, please let them read the website on mobile.
