Image Generators and Library Thing

I have now "played" with both of these. I googled "image generator" and found comicstripgenerator.com It was very easy to use, and I love Garfield so it was perfect for my blog! Library Thing is a great way for a person to keep track of their personal library--if they were so inclined ;) It is interesting to see how many other people have the same book and how they rated it. I've noticed that all of these sites have blogs. Do people subscribe to multiple blogs? How do they have the time to "talk" to their online friends and have real human contact at the same time?
