A tip from Joel Anderson:
"Here's something I think is very cool – Johnny Long, security expert and author of Google Hacking (and more) has relocated to Africa and is blogging his journey via (what appears to be) a Moleskine Cahier…"
Later revised with this note:
"Hm – on reflection, it looks like a pocket Moleskine, not a Cahier…"
Another example of how popular moleskines are.
Based on the visible bookmark on the bottom, I’d say it’s a softcover lined Moleskine notebook.
If this is a pocket size soft cover he may have some issues with sticking it in a back pants pocket, hardcovers are better for that, more sturdy.
It’s fun to see someone else who uses print handwriting.
“…blogging via a Moleskine”?! I believe that’s what we used to call journaling, keeping a diary, even keeping a memoir!
Funny how easily technology slips into our lives and the jargon assimilates into our lexicon. 
I don’t think the notebook pictured is not a moleskine.
Too large a line on the top and fewer lines to a page than a moleskine.
Anyway, I am attempting to write a journal. Though it would look funny because I write in bullet points. LOL
