Blog Title is H1 tag

Hey guys I was wondering how you make blog title in home page not be h1 tag

What's wrong with having it a H1 tag?

I'm not familiar with blogs but if it's something about the H1 bugging you (margin, padding or whatever) you could probably just change the h1 properties in the CSS.

A few more details of your project would be helpful.
If we assume that you are using wordpress and modifying the default theme of TwentyEleven then...<h1 id="site-title"></h1> to change the characteristics of it you would search for #site-title in the CSS and make your modifications there.
