Ask HN: What do you wish had SMS alerts for?

Today I found myself really wishing I had SMS alerts for certain GetClicky features(worse aesthetic design, but better UX than Google Analytics). And now I actually think I might build a tool that will let anyone get an SMS alert if someone lands on a certain page (say their Kickstarter page for example).

But after thinking a bit, I realized I would really like SMS alerts for a lot of things since my iPhone texts are the only things I check every time I get a notification (i.e. I ignore email notifications etc).

Am I the only one? Or do many people wish they had SMS alerts for a lot of things (such as comments on HN threads)? Or would making SMS alerts ubiquitous, just make them as equally not-useful as an email notification?
