It’s nice to get some feedback, especially after one has put some time into a thoughtful post, but no one is required to respond, of course. What amuses me about many OPs are the ones that ask for help, get responses, and without addressing any of them in their second post announce that they bought component X. They must have created the thread 5 minutes before they hit buy on the purchasing site. They probably didn’t want feedback but by creating the post hopefully created some clarity for their decision
