I've been working on a single sign-on project lately, evaluating both OpenSSO and IBM's trio of TIM, TAM, and WebSeal, and I noticed that Google has only 32,000 links to real WebSeal resources. By contrast, even as a young open source project, OpenSSO already has over 100,000 links.
Out of curiosity, I decided to google a variety of web languages and tools, and here are my search results:
|php||9.6B links (billion!)|
|ibm tim tam||~32,000|
I'll expand my list more when I have some free time. I'd love to see these trends over time.
