I'm sure most people already know this but I just wanted to mention a couple of technical details:

1. No information sent over ftp is secured. For this, you may want to consider SFTP (FTP over SSH)
2. Because no encryption is applied to the information, the transfer speeds are going to be greater as compared to other, encrypted transfer mechanisms (e.g. SFTP). You will probably notice a difference by ~20%. That is, if your FTP speeds are ~200 kBps then your SFTP speeds may be ~160 kBps: YMMV.

But, I use FTP when the information isn't sensitive or when I just need it "NOW"!
