I added the link to my blog on my Twitter and i tweet regularly, hoping that someone will be interested in visiting my twitter profile and eventually clicking that link.

I also implemented a proper Twitter Card support on my blog platform, so i could share my blogpost beautifully on Twitter.

The rest? I post on HN or niche-specific weekly publication (for example, weeklyosm, the signpost).

I think we need more online curated weekly publication platform that serve as a central hub for a certain niche.
