This is for the devs. It's ok when people complain. When your project catches on and reaches a certain level of use, you will be faced with an infinite stream of complainers. There's no way around it. There is an infinite supply of negative people who don't build things but just type comments. You must understand that their opinion does not matter to you. Otherwise you will be crushed by the negativity that will surround you 24/7.
You have one job: find those complaints that have actual merit. They are very rare, and most of the time they do not emerge from an angry person but a calm one. Filter information that you can make use of and ignore the rest.
What I can tell you with 100% certainty is that the complainers don't matter. They do not determine your success or your failure. They are not your target users. Compared to them they are a tiny minority. You aim for the rest. As long as you stay truthful to yourself and to your users, and as long as your product is useful to them, you will grow.
Note: this post makes it sound like that there is only negativity out there which is absolutely not the case. The vast majority of interactions you will have our positive and encouraging. Also, go to conferences. All the tough guys online are sweet like puppies when you meet them face-to-face.
