This community wiki question from 2010 showed up in the close review queue, and currently has four close votes. It asks what "good" microcontrollers are available, and invites people to share their experiences. This is definitely off-topic for the site today, but it has 40 upvotes, 35 favorites, and almost 10,000 views, with the top answer scoring +35. That's very good for an EE.SE question, from what I've seen.
My question is this: is just closing these questions the right thing to do? I don't have links on hand, but this isn't the first question I've seen in the close queue with >10,000 views and dozens of upvotes. Regardless of whether they're on-topic or not, they seem to be valuable resources. I've seen questions on Stack Overflow with a note that says they're bad questions but they're being kept for historical reasons. Can we do the same thing here? Or should these questions be locked to new users? Or am I just overreacting? :-)
