monitter is a simple twitter monitoring (monitor + twitter)
it’s quite easy to use, it can monitor “keyword” up to three keywords at a time and it will display updates (in real-time?) well, at least you don’t have to refresh the page yourself. the site is using to fetch the data and if the twitter is down, this service will go down as well, i suppose. nobody’s going to watch it all day anyway. however it is indeed a fun site to play around.
