Wait, wait, hear me out. I love the RPi just as much as the next person, however it isn't about personal feelings. Well, maybe a little. The EP&D Proposal is in progress, and we've been discussing what would be on topic should the site make it to beta, and Arduino and Raspberry Pi questions would fit perfectly.
This site has a fantastic average number of visits per day, but not a lot of questions being asked, and 100% of questions asked would be on-topic in a general embedded programming and design. Visitors would also benefit from:
There's a high probability that users of site Y would enjoy seeing the occasional question about X
Almost all X questions are on-topic for site Y
This is in no way trying to take away the 'RPi Space', or even shamelessly plugging the EP&D proposal, as I'm sure some of you may or may not have seen on already on Area 51 (No one from here is following though as of yet).
United we stand, divided we fall.
