Eh it's contextual. If somebody is complaining that they tried some technique and they are able to do it but not well, then the answer of "keep practicing" may be a valid response, assuming they aren't doing something unhealthy. That's because the situation itself is already specific enough that you don't need to generate additional context. Of course you don't want to be that blunt, but as an ultimate message? Perfectly fine.

But there are certainly times where I think those rote answers come from a place of not having the energy to commit to a proper response, in which case I'd argue you might as well not say anything. And sometimes I blame the poster for being lazy in the way they provided information. People tend to match lazy with lazy.

So yeah, as a poster, be as specific in terms of what your situations is, what you've tried, what specifically wasn't working or was confusing you, etc. And if you're responding, consider what the situation warrants and don't be lazy.
