I added to my blog a Custom Search Box (to the right) for 'B2B Media & Marketing' Search
Right now I included about 45 websites & blogs (English & a few in German). You are very welcome to suggest and add more useful sites providing good content on B2B related subjects, beneficial for our readers.
You also can include this customized search direct in any personalized startpage (e.g. for Google) and / or you can place it on your blog and / or your Website for your visitors.
