I'm planning to release an open source cms and I wonder if there is a way to know if people use it. I added this line to CMS templates:<meta name=generator content=My CMS - Open Source Content Management by me /> I know that generator meta tag can be easily faked or removed, but it'd still be great if search engines would consider this info to provide Powered by statistics for web sites.Does anything similar exist?--Edit: the aim is to know how many and which web sites use the cms. I talk about generator meta tag because to me it could be used for that. Eventually I'd be glad to know if there are alternative approaches.
