I've used WordPress to create the web presence for the Digital Gazetteer of the Song Dynasty, a digital humanities project created at UC Merced using MySQL and ArcGIS to represent and analyze change in Medieval Chinese political geography (What a mouthful!).
It's the Pressplay theme with NexGen to provide various galleries of created maps. It was important to create a web presence for scholars to download the database, shapefiles and documentation, as well as see some examples of work done with the data. Even though it isn't a blog (There may be very occasional updates about the project) I found WordPress provided the most attractive and convenient solution.
