What do you like best?
-Easy to setup and start using a SharePoint
-What you see is what you get (WYSIWYG) functionality is awesome since you are seeing in real-time how your SharePoint may look like
-When used in Microsoft's web browser it looks beautiful
-The built in web search tool is a great tool to find specific content.
What do you dislike?
-Not 100% compatible with other browsers (like Google Chrome)
-Even when it is used in Microsoft Web Browsers, it feels a bit slow, like if it is not fully optimized, for example changing from one set of tools to another can take 2 seconds, and this is not a connectivity problem, but the way SharePoint is coded
-Some error or warning messages are very vague, since they don't provide enough detail to understand what has happened
-The built in web search tool needs to be more robust and complete
Recommendations to others considering the product
If you have a company with Microsoft ecosystem, then obviously this is the solution to go, since it seamlessly integrates with other Microsoft products like Windows OS and Microsoft Office
Just be advised that seems that Microsoft has not optimized SharePoint to its full, since sometimes there are lags or delays
What business problems are you solving with the product? What benefits have you realized?
-share information across the company in an easier way (rather than sharing via email, share folders, etc)
-Implement Knowledge Management sites where several guides, documents and training material can be placed
-As a repository for always up-to-date documentation and guides, since the hyperlinks do not change when a file is updated (unless the filename is changed), then the hyperlinks are still valid
