To tag or not to tag?

I tag every discussion which I start.But I will not tag every response.I will tag if I am interested in it.The tag can help me find similar discussion,so it is very useful.That is all my view.

I always tag my replies and discussions, i think it has just become a habit and it also helps if you want to find related subjects etc

I tag on all things, unless my computer glitches. It helps the site earn money by making it more searchable, and therefore helps me make money. It also gives me reference, to look back,if I have some standard tags I use, like "myLot pays " will be one I use. I will be very generic if my personal message asks for a tag, though, like "HI"

I always tag my replies and it has become a habit for me. I think it helps in indexing..
