I have multiple sites each of which show a certain user timeline. Its just displaying information. Its not really much of an application. It just fetches the 3 recent tweets from the user timeline and displays it. This is the same across multiple websites. Is it possible to use the same consumer key across these multiple sites? If no, will each site require its own consumer key and everything? I was previously using the old deprecated version 1.0 of the Twitter API until recently when I noticed that the tweets were not being fetched.
