In my field blogs generally are thought to mean time wasted not publishing in "legitimate" journals - this is understandable even though there are so many high quality academic online creations. It's unfortunate too, for many reasons outside the scope of this post.
My blog is useful for me for gathering all of the Nights related materials I almost always randomly come across. It has been a constant inspiration for my legitimate publications and useful in my teaching. It has also been a place of global collaboration of all things Nights-esque. It's fairly safe to say that the role of a blog in the academy, however, remains far under the scope of legitimacy.
The MLA though, among other groups, has started to include digital humanities criteria for judging whether things like a blog are worthwhile. It has yet to catch on at any substantial level. The future, however, is certainly bright for the growth and centralization of online resources serving the humanities.

My blog has been cited in several peer reviewed academic writings and now a book from folklorist Christina Bacchilega (it might not seem like much but there are estimations that most peer-reviewed humanities articles are only cited 10% of the time – this article suggests 93% of humanities articles remain uncited anywhere else - alex-reid.net/2011/03/on-the-value-of-academic-blogging.html).
Here is the passage from the book –
“The fact that websites are doing more than providing a wealth of folktale and fairy-tale primary texts to those who can access the Internet is further brought home by the multiplying of online publications, like the English-language Cabinet de Fees and Fairy Tale Review (both of which have issues also available in print); discussion forums such as SurLaLune’s, which in the October 2000-June 2011 period had 3,761 average visits per day and 23,391 total posts on over six hundred different topics; blogs, including Breezes from Wonderland by Harvard-based fairy-tale scholar Maria Tatar and the one Michael Lundell has maintained since 2007, The Journal of [the] 1001 Nights; and Facebook groups like Fairy Tale Films Research” (10).
