- A highly skilled professional
- A highly skilled, non-professional
Just because someone has a very well developed skillset, it doesn't necessarily dictate good conduct. Most art / illustration forums suffer from this problem - to generalize, they will have a subset of highly skilled people who ultimately aren't professional in their conduct and reply with some severely inappropriate responses.
It's the same scenario too - when a user submits content that is significantly below the general quality standard of the community (in earnest, being a legitimate effort on their behalf), two responses are generally provided due to the difference in these groups:
- Professionals tend to ignore the content or provide some indicators of which basics to cover
- Non-professionals flame and attack the user due to their level of ability
It's regrettable but the latter often has quite a negative effect. If you can look at someones work and recognise that they are highly skilled, but not understand that they are of poor professional character, you will take on board what they say as being correct or fair.
It's the kind of conduct that stunts a lot of people who aren't thick skinned about their trade.
