From SEO point of view - is it better to have 20 or 50 or 100 posts per page? I hear it's better to have more than less (I noticed some forums even allow 100 posts), but what's your expert view on that?
I use gzip and it helps with the loading time. I've been looking around and many popular blog pages feel like 100 posts per page; still, they do well in search engines. Besides, scrolling down seems to be more convenient than going to the next page..
