There is no one answer to this question as the way that men blog varies greatly depending on their individual personalities and interests. However, there are a few broad strokes that can be used to describe the way that men blog.
First, most men blog for personal enjoyment rather than for professional purposes. This means that they are likely to write in a more personal style than women, and they may also be more likely to use humour in their writing.
Second, men tend to focus more on technology and internet-related topics than women do. This is probably because men are more likely than women to be interested in these topics, and because technology and internet-related topics are often seen as masculine concerns.
Finally, men are more likely than women to write about controversial or challenging subjects. This is partly because many men feel that they have something unique to say about these topics, and partly because many people see controversy and challenge as positive things in life.
