If you give freely without asking for thanks (and your post is considered valuable), people will thank you freely.
Asking for thanks is like a trade-off. And it is an attempt at "guilt-tripping" people into showing their appreciation, and it's very tacky.
Imagine This:
You are standing at a doorway of a store, and a lady is coming through with her arms full of packages. If you hold the door open for her and say, "Don't Forget To Thank Me!", she will probably thank you, but it won't be genuine, and she will probably be thinking, "What a jerk this guy is!"
Now Let's Change The Picture:
You hold the door open for her and just smile and say, "Here You Go, Ma'am". . . More than likely, she will say Thank You and her thanks will be genuine, and she will probably think, "What a cool person that was!"
Do You See The Difference? . . . I hope so.
