If you can find an API for any website applications, you can use the Imp agent.
Look for those with Facebook/Twitter and provide us with the API you find.
The only difference in the code is how to parse the API responses.
I would consider the term ‘website counter’ to be a website, not twitter or facebook. The methods would be totally different.
Website counters themselves have issues … whether it is site refreshes, unique visits, hot linking, search robots, … what is considered a “visit”? What does your ‘count’ represent?
We have code for interacting with the Twitter API - right now it can search, stream and tweet - but it shouldn’t be too difficult to extend it to look at the user’s profile.
