I keep a journal using text files and Vim, but it is a combination of notes and journal. Instead of chronological order, I use text files based on the subject/topic. For example, I have a text file (journal) just for "Javascript" and another for "React". In fact, I even have notes on "journaling system", so I'm updating it as of now, writing an entry about "jrnl.sh". ON each text file, I'd write down what I learned, as well as snippets and URL of websites I have encountered. I don't use "tags" that often, because sometimes I'd forget the tags, or often it is hard to maintain them. I always have a Vim of notes/journals open, and I use ctrl-p and grep to add/read/search entries quickly. I think I might have about 400 (EDIT: over 1000) text files. Everything is saved to a git repo. Certain notes are published automatically as blog posts Hugo (by adding front matter, etc). I also keep a personal journal in a traditional chronological order, which is a single "journal2017.txt" file. I also recommend using private git repo, not public, since it may contain some of your personal information, and private thoughts. For the non-technical person (i.e. not into Vim or Emacs), I'd recommend Notational Velocity (nvAlt specifically) on Mac. I'd be using it, only if it had vim keybinding. It syncs online to SimpleNote, and it makes journaling really easy.
