Is it better to guest post with or without using rel=author?

[designquotes]

If I guest post on 50 blogs, all using rel=author so they are attributed to my Google Plus account, would the links be de-valued since they are self reference back to my own blog/website?

Would it be better to guest post on a blog that doesn't use rel=author?

Google considers links from guest posts as "natural" link building, not "unnatural" (read: buying links) and won't count it against you. In fact, by using the rel=author tag and having your profile appear on other sites, not only will your post likely see higher click-through rates, but you're establishing yourself as an trusted authority on the subject and Google's actually more likely to trust your posts.
