different blogs appeal to different people. generally people probably won't find daily blogs about small details of your life very engaging ("I had a ham sandwich for lunch...", etc). But you never know. generally the most successful blogs are the ones that talk about their work and include lots of pictures. beyond that, yeah... you may not get a lot of comments. But on the other hand, it doesn't mean people aren't viewing it. whereas opening up a stand alone page on wordpress or blogspot will probably mean only your mom is reading it... :-P
