I don't know how much work this would be, but it would be nice if questions migrated from here to Stack Overflow were automatically tagged with android. I generally follow up and retag the SO version after a migration, but I wouldn't expect all users with the VTC privilege to do so. It might help prevent these questions from getting lost in the shuffle.
How many questions of this type are we talking about? How many questions are migrated from here to SO on a daily basis?
This would be a fair amount of work, and I'd need to know that it's because there are 10+ questions of this type. Often for low volume stuff, handling it manually is the best option until the volume increases.
It's also a little tricky since the intrinsic tag on this site has to exist on the target site, etc.
I see 10 questions going to SO for the month of November.
