what's a blog anyway??!!

This is my first post and I just have to ask the question, what the heck is a blog and what am I suppose to do with one? It seems everyone I know has a blog and just loves it. They tell me, write your thoughts and opinions, tell others what you think about things. Again I have to ask, who cares what I think or what my opinions are on anything? This is suppose to be fun and so here I am. As of yet, the fun has not begun......to be continued.
Just about everything I know about the computor, I have had to learn on my own. Oh, don't get me wrong, I love to give credit where credit is due and some of that has to go to my husband and son, with a little spread to my daughter as well. You would think with all these people on my side, I would have a lot more knowledge as to what I was doing here. I make many mistakes, some I can fix and others that I have just given up on. In all fairness, it's not that bad. I like finding my way around and it brings me great joy when I finally solve a computor problem and feel like I have acomplished something big. In reality, I am waiting for my 2 year old grand daughter to grow old enough to talk in sentences so she can show me how to work this machine. I am sure she will have no trouble teaching me.
I sell cottage, shabby, vintage and romantic items on ebay under the id of someplace*in*thyme. That is what originally sent me on this quest. I love making something beautiful from something vintage, old or on it's last leg. Hopefully this will be something fun I can do for many years to come. Only the economy will tell.
