99% of my blog posts are done using my mobile phone or tablet through an app called blogger (surprisingly enough), I do have a number of issues with it but for the most part it works. I use it because generally if i'm attaching a picture it's usually stored on the device i'm using.
When I use the internet to post (my blog is no longer blocked at work), when I post it gives you the option to post to google+ at the same time. As far as i'm aware not many of my friends use this so it's interesting to see that I get more views for these posts when compared to the app.
I'll do some experiments and get back to you... Or more than likely i'll forget or even more likely I won't be bothered.
