2: Old-generation worry about being deluged with STUFF

I am feeling old as I begin this 23 things class- although I am having fun and am intrigued by it all, I am worried about opening myself up to the electronic world and then getting deluged with "stuff"...like junk mail or something, like joining these I-don't-even-know-what-to-call-thems will have me fending off people or distractions. That makes me sound a curmudgeon. My computer at work wouldn't let me use Picasa, for example- a warning of spyware came up. And joining Yahoo I found a whole page of "marketing communications" I had to uncheck. Perhaps young people don't even think of this. This is my first substantive post, and it feels like thinking aloud.
