i do not bother to interlink even my own sites, unless it has some sense for user
nowadays it is all about behavioral stats... google can well make a difference between usefull and useless link
i ma gladly giving links out to websites, where the visitor will be satisfied, because if the visitor is satisfied I honestly believe google can spy on that with his metrics and then will value my website because I gave the visitor valuable content, or more accurately he spends time on the page and is dedicated to it and eventually returns etc...
If you talk to God, you are praying; If God talks to you, you have schizophrenia.
