To be short, Dblog is a blogging platform where the content makes value in many ways and that value will only return back to the bloggers. For instance, Dblog is already making value by Google Ads on the website now, and the value generated by Google Ads will be given back to the bloggers according to their DBLOD stakes.

When steemit.com makes revenue from a variety of ads, it takes all revenue but Steemians never get the rewards from ads. Unlike steemit.com, dblog.io will take all value generated with the platform to the bloggers. The team is working to diversify the profit in many ways.

That is the basic idea.
