While it is true, the return back to the pool is not a great amount.I do think the production of 10 quality blog per day is a task for a team and not just one person. It would also have a knock-on effect on bot voting reducing the number of posts a bot can upvote. That been positive or negative is still in debate.
A reduction in the number of votes which can be done by a limitation on blogs,
If 10 members posted 10 blogs and each got 300 votes that will come to 30K votes. reducing that to 5 would mean only the use of 15K votes. The value of each other vote would increase. Your one vote which gets 1 could then be worth 1.001 every little bit helps. If we do not examine these tiny benefits, the ability for new minds to join the community will diminish at an ever faster-growing rate?

I do recognise your point that the benefits are low to a system like this initially. Currently, rewards are chased by following whales and feeding off what falls away from them in the waves. Gaining followers is something which you do over time. And though some have built a massive following over time, the rewards gained from a mass following of voters regardless of the content has to have some effect on the pool.
Does anyone blogging need to earn over 1K a day?
