Don't care about what people think of you, yes, but actively think about what the impact of what you're posting is. As long as you're being some semblance of helpful at least 75% of the time, you're fine
If you decide to take the easy way out, at least do it some interesting way, like 5 fishing magnets and ropes... Run out to the space x rocket as it's about to take off.... Ohhhh add some snow skiis and skii into to space!!!
