Chrome Extension For Twitter: Twitter Watch (Real Time Twitter Update)
This tool is very useful for anyone wanting a lightweight way to watch keywords and topics, especially if they are topical memes.
Installing it will place a little blue “t” button on the right-hand side of your browser bar, which, when clicked, lets you manage your keyword phrases.
Once you’ve set up the words you want watched, a tiny number will appear on the “t” letting you know how many mentions the word has racked up. Clicking it again will let you see the mentions in full.
