This forum is as Catcrack stated up thread is an excellent resource for new routes, updates on rebolted climbs, and the combined knowledge of people who have climbed at Pinns for decades. I would not say it is good for finding partners. It is a document of an era in Pinnacles climbing.
At one point I was open to climbing with strangers I met on Mt. Project and Supertopo. After a long string of partners who were dangerous, had little or no climbing experience (and posted otherwise) or just bat shit crazy (or completely assholes with no basic social skills) I am no longer open to it. I am sure that there are people out there that have found great partners through the internet just not me. I do not have the time or patience anymore.
The best strategy IMO of finding an outdoor climbing partner is to do it in person. That could be at the spot you want to climb, joining a outdoor climbing group, or meeting people at the climbing gym. I think nowadays the climbing gym is the best bet. Go up to the desk and have them make the announcement for a partner and usually you will get other people who need a partner too. The trick is finding who wants to climb outside the gym.
