What is this?

It's a way of identifying livejournal interests you don't currently have listed, but which you might be interested in, based on what other users have listed.


Basically just for fun. But I hope it might also point some people towards interests (e.g. authors, bands) which they haven't come across but have a good chance of liking.

How does it work?

In everyday language

It finds your unusual interests (those which are shared by fewer than 20 other users), and identifies the users who share those interests and what interests they list.

Then it gives each interest listed by those users a score which is based on both the number of users sharing your unusual interests who list it, and the number of your interests which they share. For example a score of 2 could arise from 2 people listing this who each share 1 of your unusual interests, or from 1 person listing this who shares 2 of your unusual interests.

It then prints a list of the twenty highest-scoring interests on this basis (excluding the ones already on your interests list).

In technical terms

It's a perl script, which works off info provided by livejournal at


for user foo and interest bar.

A copy of the script can be found here. Feel free to modify it, whatever, but obviously credit would be nice if you do.

Why 20 interests?

Just trying to find a balance between ensuring most people would have some listed, and not making the processing time too long.

It doesn't work for me!

That could be because
a) All of the things you list as interests are also listed as interests by 20 or more other users OR
b) All of your interests are unique OR
c) There is a problem with the server e.g. too many other people trying to use the meme OR
d) You don't have any interests listed

It suggests really common, boring interests for me like 'music' and 'movies' and 'computers'

Well, a lot of people have those listed, so it's unsurprising they'll come up. If you'd like to run a version of the meme that filters out really common interests ouwiyaru has produced an adapted version of the meme here. At time of writing a Popularity Ceiling of 100000 will knock out the top 30 most common lj interests, and one of 25000 will knock out the top 300 or so.

Have you written any other memes?

Nothing that works off livejournal data, but I did write the Mystic Pig

Hmmm... I definitely second the weighting for users that have common interests, as some of those things are only moderately interesting.

cooking, writing, camping, harry potter, photography, friends, coffee, sewing, radiohead, travel, rain, sushi, swimming, jazz, theatre, dreams, monty python, hiking, dancing, french

What about a script that goes through and pulls out the interests that only one (or a few) person lists, or the interests that the most people list? *curious*

Well, the overall most popular interests are listed at

(I thought of using this as a filter on my results, but again decided it was better to keep things simple)

Granted. Twould be interesting if your script looked at the 20 interests and marked the ones that were popular, but that's yet more processing time.

Looking through the suggested interests, I'd definitely prefer the option for a popularity filter. All of them are on the "highly popular" list. :)

Yeah, I second that. Most of the interests I got were either really common or else wrong (photography? blech), but this is quite an interesting tool. Thanks, ixwin.
