I tried WordPress for a while and I gave it up. The reason is that there are a lot of plugins that are useful, but when an update comes out, those plugin customizations need to be re-updated. It got to be too much work for the return.
Last week, I decided to migrate my site over to Zenfolio. There isn't really a blog option but that's OK - I'll spend the time I used to spend blogging working on shooting pictures.
Zenfolio is similar to Smugmug. I bought a one year package and am pleased with the results.
