All Over the Web

I signed on to blog months ago---possibly even a year or more ago. Yet this is my very first blog. I have evidence of similar lack of commitment all over the Web. I wonder sometimes if I will run into myself somewhere and forget that I had ever been there. Actually, that HAS happened. But I've also ''disappeared''. Does one really disappear on the Net? Or just remain there somewhere lost in some broadband width, detritus from an abandoned web site?
