Of course we have a responsibility to the web. we are writing an encyclopedia for use. Though I know this may come as a foreign idea to some wikipedians, we're not a computer game, but a practical project. Our users are broadly defined as anyone commercial or non commercial who wants a ready reference source of general information in the web context. The web context we work in is aware of other browsers and other web services. We arent making a new system from scratch, we work in that environment, and we need to pay attention to how we are used and we need to have respect for those who depend upon us. No large information system on the web can operate in isolation from google. why this is so, and whether this should be so are separate questions, but as it is we operate as part of the present system. Wherever WP is situated conceptually or practically, it's not on an ivory tower.
