Maybe I'm missing something, but do people actually see Twitter Cards in general? I mean, how many regular Twitter users actually use the web interface to interact with Twitter?

I don't know anyone that doesn't use a third-party client. And, given Twitter's clear desire to restrict 3rd party client API access, in order to get more eyeballs on more easily monetizable web-pages, Twitter Cards are never going to be seen by many users.

Yes, a lot of people do use the Twitter web interface. An I would imagine that number will only go up as Twitter keeps adding features to it while also squeezing third party apps.

Not to mention abandoning some of the official desktop apps. Twitter for Mac is abandonware at this point.

Purely anecdotal, but the web interface is probably my most frequent means of interacting with Twitter. It does what it needs to do for me.

I see card data in the native Android Twitter app.

Oh, I do. I love getting a little bit of extra info and context before clicking on a URL. And as someone posted before, it also works really well in the Twitter Android client.

I've never used any client other than the web interface.
