So, it’s not that different from actual blogs, because, I think, most people start blogging with hopeful aspirations but stop posting well before 100 posts…
Reminds me of the discussions about quantity vs quality in artistic production. There’s an old chestnut about pottery students graded based on production volume or based on best quality of a single piece. The students who did the former also scored higher on the latter.
In this case, people might never use up their alottment for long form posts, but the simple sense of restriction and scarcity will prevent them from ever really producing the valuable thoughts, as they’ll have to create some dreck in the process.
