What is the general consensus on tooltips for web links? The kind I mean are the ones that pop up on desktop when you hover, but pop up on mobile when you click.
I fist came across these the other day whilst playing with Foundation 5 with a Ghost blog theme. Using their tooltips demoed at

I found them confusing. On desktop it makes sense as you hover and the tooltip appears, you click and the link is followed. But on mobile, I couldn't work out how to click the link. I pressed it and a tooltip popped up. Eventually after much playing I found I could hold the link then chose from the mobile Safari options of Open/Open in new page. The only reason I found this is because I was interested to find out. If I was a normal user I would probably have given up and left the site.
Is this a user experience that the general populace know about and are comfortable with, or is it something that should be avoided. My initial reaction is to avoid these tooltips, but I'm interested in if there are any good reasons to use them.
