From the article:

> Most importantly, I always send the kind of messages I’d like to receive. They’re short, genuine, and (ideally) helpful. I never try to sell anything and there’s no agenda other than to keep in touch.

You might've read that:

> So unless you have a solid system, chances are high that you won’t reach out to people regularly and miss out on a ton of fun and opportunities.

but intentionally miss the fun part and treat "opportunities" only in thebusiness context and do not allow for alternative interpretations like intellectual or personal development.

The author says it’s the easiest and most effective way to make your life more serendipitous and that if you don’t you will miss on fun and opportunities which is very true. I never go have coffee or enjoy unforeseen activities with people I don’t speak to. Having a large network of lively relationship is indeed a sure way to have more things happening in your life. Also people enjoy other people reaching out to them. Once again there is nothing unusable in what OP is doing. Having tools to help you keep in touch with people is a necessity in any position where you need to maintain good relationships with a large number of people. It takes effort and is a good thing.

Yes - opportunities for house parties, for new flatmates. For joining a D&D group, or a sports team. Maybe for a new job, or a new hire. Or even a future partner.

I don't read it as being the goal. More like one of his motivations.
