How to add my blog to this forum?

Look at 'recent blog' below my username. Why cannot transfer to the web page instead of a XML file? How can others do it?

 

1. If it is not XML, I dont think you can since only supported will work
and:

2. or you can doante to have custom title where you can post link

3. and signature section is where web links are for

4. If you mean why some's blog feed direct to home page and some direct to feed, it depends on the blogging script you use.
