Normally I'd say you're being too cynical, but in this case it really does look like little more than a recipes-only (social?) bookmarking service.
I think the reactions you're getting are likely focusing on this project as a useful product or a business, not a coding exercise.
Because it's well-trod territory, with existing products that have been around for years, you're probably seeing more negativity than you would have if we all knew this was a learning project.
That said, not every step of every coder's learning process is broadly interesting to a community of people who have been programming for decades in some cases.
Usually these kinds of posts are better received when they come as a blog post about what the person's background is, what they were trying to learn, and how they felt about using those tools for the first time.
