Drupal vs SharePoint

Drupal is a free and open-source content management system (CMS) and content management framework (CMF) written in PHP and distributed under the GNU General Public License. Unlike alternatives it's often used for knowledge management and business collaboration. Because of this plug-in extensibility and modular design, Drupal is sometimes described as a content management framework. Drupal cloud alternatives are Wix, Weebly, Squarespace
SharePoint's multi-purpose platform allows for managing and provisioning of intranet portals, extranets and websites, document management and file management, collaboration spaces, social networking tools, enterprise search, business intelligence tooling, process/information integration, and third-party developed solutions. SharePoint can also be used as a web application development platform. SharePoint alternatives for small business are: Office 365, Box, G Suite, Zoho. There are also free open-source alternatives to Sharepoint - Alfresco, Nuxeo, Liferay Portal.
Comparing Drupal vs SharePoint is like comparing apples to oranges. Because your business is unique and nobody except you can decide, which is better for your company. But we can add some fun to your research and suggest some new comparison parameters.

2000 - Groove pushes sharing ideas on the Net - a new advantage over Drupal

Groove Networks takes the wraps off software for collaborating over the Internet. Groove brings together a number of disparate computing concepts that have been floating around the Internet for years, such as home and corporate video conferencing, the exchange of music, video and photo files, and instant messaging and chat, among other things. But rather than making consumers and businesses use several different products for these activities, Groove has bundled the functions into a single product. Groove will also sell the product to individuals and consumers. The company envisions families sharing gossip, photos, music and other information despite being separated by long distances. The software creates a shared space on a computer for files that can be shared with other people using Groove over a corporate network or across the Internet. Napster takes a similar approach to sharing music files, which are stored on individuals' PCs but accessed through the company's software connecting through a central server.
