I don't usually share about Bitcoin and Bitcointalk among people but I shared this forum as well as Bitcoin, with some of my friends, and that was years ago. And it will complex when they come here and try to find out their answers about cryptocurrency. That's why i personally told them and explain them about Bitcoin and this forum. Thus they gradually know what is Bitcoin, cryptocurrency and what is Bitcointalk, and how we discussed here and help each others if need.
There is nothing wrong with referring people to the forum because they will join, if they like it, they stay, and if they don't, they leave, you won't have any problems or obligations or anything, but when you suggest Bitcoin or cryptocurrencies to people, you need to understand that their profit and loss will be your responsibility, which means that if they get profit, you might get some praise for them and some appreciation, but if they lose money in it, you will need to face the blames for it.
For me, I don't do any of the two. I don't want to force anyone to do anything, if someone asks me about a place where they can learn about Bitcoin and cryptocurrencies and everything in general about this industry, that is when I might suggest this forum to them, but I wouldn't do it myself.
