At some point over the next few days, we will be making changes to the URLs used for all journal content due to a new security vulnerability in a popular browser. This will affect all accounts on LiveJournal, although no changes will be required on your part. All of the existing URLs will still work, though redirect to the new URLs. When this change is actually made, we will be posting more information to news. We also will then be following with a much more technically oriented post in lj_dev.
