Last twohree blogs on main page of CF shouldn't be on main page. And it become quite common thing in recent CF practice. Main page should contain only something that all users should see. Of course, round announcements, platform upgrades and sponsor posts should be on main. Blogewoosh had some rights to be on main because it was cool series of blogs which had chosen CF as its platform so CF should have praise it (but it would be nothing wrong for it to be just in [user:Radewoosh,2019-03-28]'s posts like everything else). But all other stuff? Let's look at some examples for the last year.↵
