To keep the load on our database server light, the following limits are currently imposed on the interests list of each user:
* There is an overall limit of 150 interests per journal. * Although an interest can consist of more than one word, the limit is four words with single spaces between them. * Whether an interest is one word or multiple words, there is a 50-character limit per interest. If you submit an interest using more than 50 characters, it will not show up on your userinfo page.
Users with "Self-committed" [paid] or Permanently Insane accounts also have the ability to search for journals based on similarity of interest (the number of interests in common with a particular user) at http://www.insanejournal.com/interests.bml?mode=findsim .
