I set up profiles on both WordPress and TravellersPoint and then created test blogs. I think WordPress has a slight advantage as to ease of use. On both of them, I've found it difficult to deal with photos. It's easy enough to insert them into a blog entry (once you've uploaded them to a gallery), but giving them names and descriptions just isn't as simple as it was on TravelPod. Also, on TravellersPoint, I figured out how to add a title and description, but if the photo is "big" in the blog entry, none of that info shows up. If the photo was inserted as a thumbnail, then the info shows when it's clicked and enlarged.
I'm also really going to miss how easy it was with TravelPod to let your readers know that you posted a new entry. With both TravellersPoint and WordPress, it looks like the easiest way is to copy the URL, open your email program, and then send an email to your readers. It's not a huge deal, but it is an extra step. Maybe I'm just missing something.
I like the idea of TravellersPoint, but WordPress definitely has the edge at this point. I'll keep playing around with my test blogs.
