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, just for completeness sake, here's a link to three months ago in my other journal.
Looking at my archive is instructive -- in the last couple of months, I've gone from averaging maybe two or three times a week to more like two or three times a day. Merging this journal with the other has something to do with it, I'm sure, but I think it's mostly just that my community here has gotten larger and more active. I hope I'm not boring you all to death with my newfound tendency to blather on here. :)
