Don't forget that you can specify related pages as <link rel="next/prev" /> and let the browser handle pagination.
I recall when I used Opera, you could scroll down, hit space, and it would go to the next page as long as the website provided that information (forum softwares often do.)
I also mentioned the column width because this site has the obvious problem of long horizontal text, which is a no-no. People naturally read in chunks of 10-15 words scanning vertically. Long, horizontal text is easy to lose track of location.
How much have browsers invested in their pagination solution, though? If I specify that tag on my pages, does that mean users who visit my site will have an awesome experience when it comes to pagination?
