After making a video for my blog when I watch videos , it seems not attractive. So I do not know how to make a blog interesting? How to talk with camera for long periods of time? Please advise me about video blogging only, not general blog.
Try to use screen capture software first like Camtasia or CamStudio. For video blogging, you need to have a high quality camera and you should be professional in speaking to the front of your camera. Screen capture software is the first thing you must do, as a practice. Headphones with microphone are fine, you can just edit the volume at Windows Movie Maker.
Not much to add really, all I can say is "Practice makes Perfect" just shoot a few practice videos, maybe a few times a week, once you feel more confidant, try shooting for real. I had the same issue, you do get better and to be honest it is probably just you, they probably look fine :
