Twitter Common Friends

For the past couple of months, A lot of people (who I don't know) have been following my twitter.. Mostly they don't look like anybody I know, not even Egyptians, & I'm not that popular anyway.. I'm ok with people following me anyway.. My twitter is public, & I'm not planning to change that.. But sometimes I need to know if these are real people who are in my twitter "social network" or just some sort of zombies or bots..

I've just created a small app to act like "common friends" in Facebook so I can find out whether I really know them or not.. Actually a couple of these followers are really interesting people & I'm following them now.. The app finds common people you're follwoing.. not common followers, the followers all is almost the same it just need authentacation..

The application depend on a single twitter API which takes the user name as a parameter & returns an xml (or JSON) file of their freinds for eg these are my friends xml file:

I used the "XML schema definition" tool (Xsd.exe) to generate the class to use the xml nodes directly as nodes rather than querying the XML document.. I'm such a lazy coder.. I know :D..

Once the xml is deserialised into the users datatype like this:

XmlSerializer oXmlSerializer = new XmlSerializer oXmlSerializer = new XmlSerializer(typeof(users));

users oUsers1 = (users)oXmlSerializer.Deserialize(

All you need to do is to find the intersection set between the two list/sets.. & display them The source code & binaries are available here:
