What is the point?

You tag them so you can find them again. It's a way of organizing things and it puts things in search engines.

I don't usually tag the discussions. I did when I first started posting here, but then I realized that it was often harder for me to figure out what to type in for the tags than it was for me to type the response, so I stopped doing it. I don't really know if it helps or not, but I usually don't do it.

I always tag my discussions, and I try to tag everyone's. Its a good way to get your discussion noticed, as it puts it into different categories.

I most times tag the discussions. I think that it increases the chances of your discussion being put in the similar discussions section so more people will respond. Also if someone is looking for something with a particular topic they may be able to find it.

actually i not really noe y v hv 2 tag the discussion... but sometime i will just tag it coz i wish to noe wat is the difference... now i still not so familiar n still trying on all tis stage...

I do tag it sometimes. Although not most of the times when i am responding to discussions since I find it a bit difficult to put keyword to some weird discussions. But when I am starting my own I try to put alot in so people can search for them easier.
