One thing I don't like about jekyll (unless I'm missing something), is that on site generation, the last modified time stamp of the files gets updated too even if the file content hasn't changed. This way a FTP program like Transmit will not be able to synchronize only the modified files.
Just about everything that supports ftp supports ssh+rsync. I'm not apologizing for the bug, but rsync+ssh is a sane default for synchronizing everything everywhere these days and sidesteps the problem almost entirely.
