If you've asked a question and people have taken time and trouble to give considered answers, possibly with links, it is nice if you reply. It can be a simple thank you for all the replies, or a follow up as to how it all turned out for you or a comment on what you have decided. You can also "like" or "agree" with replies.
You don't have to thank every single person who replies to you, a general response after a few replies will suffice.

Having said all that, if you would like to drop a bottle of wine into my inbox, to show your appreciation of my reply, that will be fine.
