I just hate how FB messes up the order of posts to favor ones that have gotten a lot of attention, vs chronological order. If I see a question, then find the answer, I can't find the post again because it's dropped off in favor of the 20 "hey look at my car" posts that have gotten a lot of attention.
FB is good if you need an instant answer on something simple, or want some opinions on what headlights look better.
If you want a deep technical answer, you are better off coming to a forum. I gave up writing out 5-lug swap advice after typing the same thing 3-4 times in a 2-day span.
