I’d like to add that the way you are responding and even opening the ideas up more in the comments section, keeps the thread going and may provide more ideas for a reader. Sometimes a post gets a few responses and just dies, frequently because everybody just wants to get their 2¢ in and they aren’t really taking in the whole conversation.
This is great comment-generating advice! Whenever possible, I ask questions at the end of my posts in order to invite comments, and I also try to pepper questions throughout the posts as well. The questions come naturally to me as I’m writing (I’m curious by nature), but I think they serve well to stimulate readers and prompt responses.
