Fossil's also very easy to put online, needing at a minimum a two-line bash file to function as a CGI script. Maybe more relevant to private data, the builtin wiki makes a good personal knowledge database. The next version of fossil will have a forum (seen already at https://fossil-scm.org/forum/forum https://fossil-scm.org/forum/forum ). With the time sorting for threads, that might be good for temporal data that you wouldn't want to put in a wiki.
