If you don't like his question, don't answer, but finger-wagging over commas and punctuation makes you look bad.
I don't think it's too much to ask to just proofread before you submit.
That's an important life lesson as well.
A foreigner does not need a perfect English (or English at all) to create and sell a product in their countries. Please keep in mind this is an international community.
Foreigners should not be discouraged because of a broken English.
Which worked out great, because otherwise most answers would have been specific to OP's emotions and interests and probably wouldn't be that useful to other people.
Questions like this don't get upvoted because of the effort put into them. They get upvoted because of the answers they attract. I'm fine with that if it means I get to read some interesting answers.
It is indeed low effort.
Your comment may be more insulting than the one you're replying to :)
I have seen people reply with so much consistency and grammatically well-formed sentences I almost cringe how they have honed their craft to this level. What's the secret? Any ideas on how to work on improving writing skills especially in formal settings & forums.
PS: had a boss who was so consistent in his writing that he used to reply in full sentences even on IM with punctuation and all that. I secretly admired him.
PPS: Is Grammarly premium worth it?
For one, writing skills are important. You will have a hard time selling your project to anyone on its merits if you write incomplete sentences with lackluster English.
Second, you haven't taken the time to list out what your strengths and domains are, therefore HN can't leverage its vast knowledge to point you in the right direction.
If you want to build a useful project, you'll need to be more detail oriented and persuasive than your post here. Take the time to do things right. Feedback is worth its weight in gold, and you've given us zero to offer feedback upon except for your scanty quick query.
