If you go to the home page of my website you will notice a status bar in a marquee tag.
I got an account at status.cafe and use a bookmarklet they provide to update my status. It's really very easy.
I would have built my own tool but the code that runs status.cafe is open source and everyone else on there has a funky website and I don't think it's going anywhere anytime soon :)
Still update twitter but this is for more personal things? To be honest I'm not sure what the difference is going to be but it will come into its own I'm sure of that.
It's in a marquee tag because they are cool and more people should use and abuse them.
