Recently Blogger introduced a system called auto pagination, which automatically adjusts the number of posts displayed per page, depending on the size. So instead of a publisher deciding to display, for example, 500 posts on the top page, and taking a considerable length of time to load, Blogger will automatically set a limit to make the page size more manageable. A page would load much more quickly. Or that is what I understand to be the case.
Blogger Buzz: Auto Pagination on Blogger
It is unclear how this is done, and what is the limit imposed by Blogger. As such, it has caused some confusion and anger from some bloggers whose blogs no longer look as pretty or professional as had been intended.

I believe it is perfectly within Blogger’s right to introduce such a change in priciple, though as with Buzz, it may have been wiser to test this feature more widely, before introducing it generally. A clearer explanation of how it works and what are the tests imposed by Blogger to determine the length of the page would have been also welcome.
Perhaps the main problem is that Blogger has placed emphasis on the visitor experience in explaining why it has decided to introduce auto pagination. This concern for speed and visitor experience makes sense, but it naturally annoys some publishers, since it can be argued that such matters ought be the bloggers’ decision and not Blogger’s. Many bloggers are very proprietary about their blogs, and what they want takes precedence over visitor experience. Blogs are quite often about the bloggers and for the bloggers themselves, and not necessarily for the visitors.
