I just joined Plurk

What's it all about anyway? Sometimes I can be impulsive. But a couple of knitters of whom I know thru their blogs belong and are having fun, so I wanted to know what's it all about. I ended up joining before I knew what I was doing. My name on Plurk is JunieBird (an old nickname from a now departed friend). I have yet to figure out Ravelry, so hold out little hope for Plurk. Guess I'm just not "computer savvy", make that "computer illiterate". Well, at least I've got the Blog thing figured out (maybe).
