Just wanted to add my $.02:
I have a island with many buildings. Probably more than most, maybe not. However, I'm starting to find the maintenance rather tedious. Ok, *really* tedious. Particularly the wheat fields and wells. The few buildings to mitigate this, such as the waterwheel or silo, just don't make any noticeable difference. TBH, I don't see myself continuing much longer unless there are changes on the way. I've already taken a long break (as have all my friends).
And, last but not least, the 400 item limit on trades is giving me RSI
