I've been looking for an alternative to ezines, squidoo and hubs for writing articles with links to my site. I've found a couple of dofollow link sources that might be of interest to people.
Prospotlight allow - even encourage - you to promote your own website and give you your own blog page. Links are dofollow and have shown up on my backlink checks.
travelling seos gives you your own blog page with dofollow links (though they haven't yet shown up in my backlinks).
NB - I don't own either of these sites.
