It's fine to occasionally post links to your own work when it's relevant. But it's not fine to do it routinely or generically—HN readers consider that spamming.
Since you haven't posted a Show HN in two years, you should try again. "I built Kontxt.io to save, organize, and share the best parts of the web" is a good line - you should rework it (shortened) into your title. See https://news.ycombinator.com/item?id=22336638 for tips and https://news.ycombinator.com/yli.html for advice about how to present your work to HN. Email hn@ycombinator.com with a link when it's up, in case we can help. Good luck!
