I held a session with Dag König on the basics of Web Role and Worker Role and promised to put the code for the “Twitted Demo” on Codeplex so that those who were interested could work on the code together and transform it into something that would or could work in a larger scenario.
So I put the code up on Codeplex and called it Another Azure Demo Project - http://anotherazuredemoproj.codeplex.com/.
Feel free to go there, and request to join the project if you like!
The initial version of the code is made as a simple getting started demo, made for one instance of a web role and one instance of a worker role. The code has a worker role which does a search for specific words or tags on Twitter and stores the number of hits for that word in a table storage. A web page displays the number of hits per minute in a graph. This hand/mouse written sketch should explain the overall idea pretty much I think/hope (it's sketchy on purpose :)
The Future Version
The idea is to make the code grow into something that is more "Azureable", something that would support multiple instances of the web and worker role. I've not worked out the final scenario yet, but one place to start would be to support searching for loads of tags, and have the search distributed between multiple instances of the worker role.
