You, me and others know that Product Hunt isn't just a directory to showcase and publish your apps/websites/startups/products, but a spotlight that has many benefits when it comes to the IT industry. Nonetheless, all these alternatives are good, and thank you for gathering them all in one place.
The value of Product Hunt is controversial. Founders spend a lot of time hustling for upvotes to reach the top spots, but the traffic they get might be comparable to a single Hacker News post. Perhaps the most valuable thing is the badge, but when everyone knows it’s earned through vote-pushing, who really cares about the badge anymore?
To who? I guess you are referring to indie founders here. When the badge is placed on any site (no matter how one gets it) it gives users and VCs some sense of trust.
