When I want to migrate a question, I get this dialog:
Unfortunately there no description of the site or its scope at all, only its name. Something like this, for example, would be a lot better:
In the case of the Android site, the scope is rather unexpected. I, for one, would have simply assumed that Android programming questions would be on-topic there.
Given that there are now 150 sites (and growing), it is difficult to be familiar with the scope of them all. Yes, I could go to the site and check the scope, and that's certainly something I would do in case of doubt, but just making the wrong assumption about a site's scope is an easy thing to do, and can be fixed with one or two lines of description. Right now there is no context at all. Not even a link to the site; I even have to figure out the domain name by myself.
Note: this question/request was provoked by a discussion in the teacher's lounge prompted by confusion over the scope of Android Stack Exchange.
