The BLOG button is sorting blogs correctly when clicked, but the LAST POST and POSTS buttons are not sorting blogs correctly when clicked on this link.
The "allblogs" page has a number of bugs that we have been working on. Hopefully we'll have a fix deployed soon so a person can search and sort correctly.
This bug is finally fixed!
You can sort by Last Post and Number of Posts and when you start typing in a keyword in the Search field, blogs with that keyword in the title will render.
