RSS...?

you know how nearly every site now has this button:

or "subscribe to feed" button...
well.

that is RSS.

after making an account with bloglines or google reader or the many more sites which i'm not bothered to find out about,
you can go to your favourite sites and find and click on the orange button or the subscribe sign.
then
you go to your account and all your subscribed sites can be found on a list.
it also tells you when the site has been updated SO:
you don't have to waste time going to these sites everyday to check if there's something new (ie. saves time) , AND
reduces your internet downloads because you don't have to go to those sites to check!

message: rss is good.

here's where i got all this very-well explained information.
the video's VERY simple and clear and not that long.
