I had a "hire me" link on my newsletter for a while (I recently took it down, because I am not available for the next few months). It seemed to be a moderately good strategy; I got multiple offers quickly after I got laid off.

Monetizing my newsletter doesn't sound appealing, but trends.vc seems to have a pretty successful thing going on.

I highly recommend reading this post from Ben Kuhn on the how and why of keeping a blog. Rather than focusing on a niche, it gives great advice on finding things to write about. Maybe start out developing a style first, and see what niche develops naturally?

Thank you for sharing

I have built https://microsaasidea.com to 25,000 subscribers and is one of the fastest growing newsletters around SaaS. The newsletter talks about various niches that Micro SaaS builders can pick up. It kind of covers various Micro SaaS trends, opportunities, technical chops, marketing chops, cost analysis for every niche. We have more than 1000 ideas covered with data points and it's growing fast.

I recently also attached a closed community for the subscribers where we talk about a lot of experiments, MVPs and trends.
