To connect with others in the best way possible is to of course "interact". There might be instances where people wont like what you say or suggest but then not everyone thinks on the same level. What may be is good for you might not be the same for others. Its ultimately up to you if you can differentiate that.
I personally talk and interact with many people, but I never try to take anything personally. The best thing about being in a community is that there are people from around the world, which is great. This can also lead to different beliefs and thinking. Just always be respectful and keep everything simple : these two I think are the most important things to keep in mind.
There are always people of different ages some old, some young so you never know what might trigger whom or who might not feel good about what you say, by being a bit careful we can always keep the community healthy and strong.
Also helping others is always good , be it in any way possible.
