What are the limitations on the amount of data on github pages?
Main github repo a limited in 1 GB (https://help.github.com/articles/what-is-my-disk-quota/), and what about github pages?
UPD
On http://www.quora.com/What-are-bandwidth-and-traffic-limits-for-GitHub-pages I found two much different answers.
GitHub now has new policies of a 1GB filesize repository, warnings for pushes of files over 50 MB and complete rejection for fileuploads of 100MB. GitHub warns you when you push a file larger than 50 MB.
