[UPHPU] Best way to incorporate blog into web site

[MilesTogoe]

okay, we really want to have a company blog as part of our website and 
looking for advice as to the best way to do it.  I guess there are options:
1) build the website around the blog (ie use something like wordpress 
and have the blog dominate - a la tompeters.com
2) insert the blog into the web page (not really sure how to do this)
3) have blog on separate linked page and use blog software or service 
(wordpress, blogspot)
4) build own blog as a separate page on the site using php or rails or 
python - this seems like what 37signals is doing with their signals vs 
noise blog (one of my favorites)

thoughts?  examples ?
