In those sort of uptake scenarios a IMO lot of the blogging records will go to the 2nd layer. And the main thing the first layer will be used for is governance and immutable account verification (ie verifying the person posting and their followers) . This already happens; we currently don't post images or videos to the blockchain they are stored by 2nd layer third parties . As congestion goes up long form text will be next. A hybrid would be just to have the first 60 words get allocated etc.
