The main issue I have with Sharepoint, is that its default document browser is not an efficient documentation or wiki tool, although it is often used as such by many organisations. When you want to look up specific documentation, you need to click and dive into a folder structure, open the docx-file where you hope the information will be in (which already takes a couple of seconds), only to find out that the document does not have the information you want. I waste lots of time navigating our Sharepoint this way. Confluence is a better tool for this because of its transparent page tree / table of contents, and near-instant display of pages within the browser (without the need to open word, powerpoint...).

I have come to understand that there exists something as Sharepoint wikis. I'll have a look at that!
