There are many softwares which can help you schedule status updates on Facebook and Twitter but here I’ll talk about 3 online services which can help you schedule updates on Facebook and Twitter without installing anything on your computer. This is especially helpful when you’re on a public computer and are not allowed to download or install any software on the computer.
