Once your blog is up and running, it can be really useful to link it up to your other social media presences.
Feed your blog posts to Facebook via the Notes page on Facebook ( http://www.facebook.com/editnotes.php?import )
Create a link from your existing website to your blog, or use your blog’s RSS feed to bring content into your website (note, you might need to enlist the help of the person who looks after your website here.)
Think about updating all your sites at once, through a platform like Ping.fm
...and vice versa Use Blogger’s Gadgets feature to add your Twitter feed to your blog. Or to feature your Flickr (or Picasa etc) photos to your blog. Add Blogger’s share buttons (in DESIGN>PAGE ELEMENTS>BLOG POSTS) to let readers share your content with their social networks.
