More often than not I think we worry to much about profitability and social-acceptability while building applications for the web. As of Web2.0 we're suddenly deluded with social apps that only harness user's in terms of output, meaning applications that allow users to socialize with one another via the apps API; IMHO, this just creates more noise. We need web apps that harness users/user input for creating better output. This sort of thing can be built directly into existing APIs or built from scratch where the user is directly passing vast amounts of data as input. Current web-apps are weak in this regard, since the input we ever pass into the system are either shouts or bookmarks.
