I think only Twitter accounts that have a good reputation and also Twitter have people who have long worked in the crypto world that can be followed and trusted as a source of cryptocurrency information. if you are new to cryptocurrency then I think it will be difficult to get followers. Many cryptocurrency users use social media like Twitter and Facebook to share info about cryptocurrencies. so in my opinion making Twitter as cryptocurrency information is not wrong.
It depends as I don't depend much on twitter although they are reputable or not, still I don't agree that we should trust them as they can say whatever they need to say and to show to people for them to impress their followers, so aside from twitter it is better to ask in their community too and to update or ask about the current status of their project, also doing research alone is a good one.
yes you really better if asking about the crypto project directly ask the project community. but what is discussed here is about crypto in general about price developments or also about certain coins. at the moment most crypto users have twitter and they use it to share information about crypto I think it doesn't matter. and of course we can also rely on this bitcoin forum to find information. I think the more sources of information the better.
