Twitter help!

Can you all hit me with things I should be doing/taking part in on twitter to promote my items.
I know there is folksy hour, but what do you actually do? Is it just that there’s likely to be a lot of folksy content tweeted at that time, and I interact?

Sorry if this is really stupid question, I am new to twitter!

Are there any other “events” or hashtags I should be using.

So far I have followed a lot of other crafters, been retweeting things i like etc. Is that all I do?
