I switched to TW for journalling, but it's still not perfect. Before that I had just a text file I could press a button to insert a date and add some text in at the end.
I switched to monthly journals rather than daily as with daily there were just too many small tiddlers. I think you need a lot of discipline to categorize every thought you get in a nice hierarchy, and that takes time. I've started using the "Excise" command for that in TW, that lets you pick some existing text and move it to another tiddler, maybe adding a link (here the backlinks would help, so I might upgrade to Stroll, if possible)
