A LiveJournal Culture Guide
Short, concise description of the idea
Something I've seen come up in discussion with a number of users (especially newer ones, and especially in light of some of the conversations about the removal of invite codes) has to do with the idea that new users may not understand some of LiveJournal's culture.
Some kind of 'official' (in the sense that it could be pointed to in Support answers and related discussions, nor in the sense of mandatory reading) could be very helpful - it would also provide a place for people new to the site to learn a little more about aspects common across the site, but which are cultural, rather than technical.
Full description of the idea
I see this (though I can see a number of variations) as having a brief explanation emphasising that LiveJournal is largely volunteer run, some explanation about Open Source, and some other basic information of that kind that affects general attitudes about site management.
Then would follow some basic and very general outlines of some different areas - not so much 'how to' (which the FAQs cover very well, in general) but 'where you might look for some of this information or some background'
For example, a section about how Friending works might say something like (this is a rough draft, obviously):
"There is a lot of variety in the way that LiveJournal users manage their friends list. Some people add only others they know and trust from other places online. Some people will add anyone who asks. Many people are somewhere in between these two points. Some people keep tighter limits on the number of people they list to better manage their time, others will list anyone, but may use filters to only read a small portion of their list regularly.
The best way to find out how a specific person manages their list is to ask them. Some users also list this information in their User Information page, or may create an entry that is always at the top of their journal which explains how they handle this.
For more information on how to manage your own friends list, see [relevant FAQs]"
One on communities might include something like:
"Community rules are set by the maintainer of the community. If you don't like the way a given community is run, we encourage you to create a new community with a similar focus but different rules. The Abuse Team can only interfere if there are Terms of Service violations in a community - not simply if a maintainer is unfair or if there are violations of a community's specific rules."
Bits I could see being of use (and I think there are probably more - these are just ones I know I've heard come up over time and which aren't really answered in FAQs clearly, or where they're buried in FAQs that people new to the site might not read/realise are useful.
* emphasis on the largely volunteer run bit and what that may mean in terms of response time (both in terms of Support/Abuse and in terms of response to issues in communities).
* about different ways people handle friending and some places to look for more info (i.e. user info, etc.) I've heard a number of people new to LJ not be sure if it's ok to friend someone without asking them directly first - new folks don't always think to look in the user info or don't know if it's ok to ask.
* that only a very few communities are 'official LJ' communities - the rest are volunteer run, and maintainers aren't required to be nice, allow everyone in, or whatever.
* that LiveJournal has a philosophy of trying to give as many options (for dealing with harassment, etc.) to individual users as possible, and encouraging self-reliance as much as possible. (But that there are further resources if that doesn't fix a problem.)
* that with over 700,000 active users, not everyone's going to get along. That's ok and expected - that's why the tools (and other resources) are there.
* general overview of resources (link to the FAQ page, link to the social contract, maybe a few others) so that people don't need to try and figure out what's where.
Again, I'm sure there are others.
