Chances are people you don't even know are being introduced to your journal every day, either randomly or through someone else. In addition to recent entries, people can get to know you better by what you posted in the past. With that in mind post a link to your entries on this day three months ago, six months ago, nine months ago, a year ago, and two years ago. If there was no entry on that day, link the closest date.
Three months ago: Nothing on the 23rd, but there are many posts on the 22nd and 24th.
Six months ago: 1 entry
Nine months ago: Some posts as well
A year ago: A couple of memes and the most important banner ever
Two years ago: Nothing on the 23rd again, so 22nd and 24th will have to do. There's even a poem!
