Hey,<p>Been looking at developing a commercial business-focused web application and general collaboration and file sharing seems to be the only useful thing that comes to mind. It seems the space is extremely crowded a number of big players already, providing some nearly impossible to beat software.<p>As crowded as the field is, it also seems to be relatively untapped as an overwhelming majority of businesses use in-house software, prefer not to use anything, or simply don't even know what the internet offers yet.<p>Any thoughts on the current market for business web applications as well as trying to jump into a well-established market such as this one?<p>Thanks as always..
