Yes, you can learn a lot from the project website. But it's good to find different sources of information when you want to invest in something. Also, it is good to know what people are talking about it through, e.g., social media.
I tend to agree but make sure the group is genuine.
I've done this before, I joined a bounty campaign such as social media and I followed the progress of the project but I saw in their social media don't have genuine members, there was no clear engagement and it should have been discussion engagement on their social media profiles. Ask yourself,
"are there active discussions and responses from the community, or is it just a one-way conversation?", and lastly, check if their followers and engagement are genuine or if they have purchased fake followers or engagement, same as Twitter or more worse Telegram.
So you must be careful also what you're following on social media.
To check if followers of a project are organic on a social media is a good measure to avoid scams. This way you can relatively trace the profile of the investors of that project: they can be dived into the technical aspect of cryptocurrency, they can be wealthy investors, average crypto investors, just bounty hunters or even bots, that is the worst of the cases, meaning that project must be put aside at all costs.
On the other hand, to have a loyal base of followers isn't always a positive sign, because it turns into a cult where reason and logic are neglected in order to raise the idolatry for the project or the person behind it. Projects like this must be also avoided. An example is the Celsius, plus CEL token fiasco.
