Webscrapers is basically the short name for us. A bunch of people that are interested and knowledgable in web scraping, HTTP scripting, bot writing and internet spidering. For fun and profit.
We have a mailing list setup for discussions and questions around issues within this area.
We started this on July 2nd 2010. We are already over 70 subscribers, and among these we have two of the authors of the books mentioned below and the primary author of curl and libcurl.
