If you have dealt with real people and you know the difference between what's truth and what's not, then I guess you already know your answer, you have the talent to pick the right ones only on yourself...
Research first, then go for anything...
There will be many information and so are users, you can ask any trustworthy member of the forum who are helping everyone all the time like Amph, notlist3d, theymos, and you might even try your luck by asking for something you don't know about Bitcoins in Bitcoin discussion to get it resolved...
ya , you are right in real life how you trust anyone like that same here you have to imply same rules, talk with peoples here on any thread which gives your query answers, before trusting first for some days you have to check the forum properly and read most of the thread and then you can know that how scammers work and how you can get saved,
There are all types of topic through which you can gain full knowledge about bitcoin and its technology. Their are thread which gives you details about the scheme which is good and which is bad. and mostly dont trust negative trust users.
Best of luck
