He can somewhat type, and part of my goal with him doing the journal is to practicing writing and typing. I'm not too worried about it being kid-friendly as DS and my older DD are quite good at figuring out technology. I know we could just use the Notes app or the Ginger software which we installed on the iPad, but I thought it might encourage him more if it was geared toward travel. Spell checking would be a bonus as he is more likely to type if he can get the help with the spelling.

What software/site did you use for the blog?
