I certainly wouldn't be able to! As Vaith said, it could be done if one creates short posts, but those posts will probably lack substance. 

There are however instances where someone might post up to 10 times or more per day and still create relative and informative posts. One such example might be someone blogging about up-to-date cryptocurrency/stock trends. As the the values in this area are constantly changing, it is necessary to post frequently. This doesn't usually take as long as creating original content, as they make use of a template and only adjust only certain areas, apart from writing their analysis

So yes, for the average blogger 10 posts would be quite a lot! It's better to create fewer posts that actually bring value to the community. People following you would also enjoy your posts more if they don't feel like their being bombarded.
