You can just edit the comments online - NOT THE BLOG's POSTS! You should set this post as an IDEA post - because this function should be a part of some (hopefully, near) future update....

Please note this >being able to write/publish BLOG posts online - would be a HUGE advantage in selling the BLOG containing website to the client!

Hi John, 

I confirm you need to use the program in order to edit your Blog posts, then export the changed online. Still, you can use the Dynamic Content Object to create online editable texts. 

Please let me know if I can be of further help. Kind regards.
