I have been on LiveJournal since 2001. I have had a Permanent Account since 2005. Many of my friends have used it for similar amounts of time. In the past few years, I have migrated my posting and reading off of LiveJournal. I do most of my blog reading through Google Reader, but still have a number of people I want to follow on LiveJournal. They often post friends-only entries that are not accessible from within Google Reader (really, from nowhere outside of LiveJournal). What I really want is a way to get each of my LiveJournal friend groups as a feed that contains both public and protected entries. This is what LJProxy was designed to do.
LJProxy is a PHP-based web application that you run on your own server. Server requirements are light (look at the project page for details) and installation is easy. This server acts as a proxy between LiveJournal and Google Reader.
I threw this together over the weekend and have run it long enough now that I feel confident that it at least does not have any egregious bugs, so am releasing it as a GPL’ed Open Source project.
Exact details, installation, theory,security concerns, and downloads are on the project page at https://netninja.com/projects/ljproxy/
