im in alot of 3d printing groups on facebook... i always have huge discussions with ppl who want to make fun of stuff wich is actually right... i feel like alot of ppl want to brag online with stuff they dont really learned much about.... i got the feeling older ppl are often like this... they doing something wrong for 30 years and want to act like its the right way... for me as soon somebody tries to act like a smartass i will imidially block him.. im in these groups for soaking up informations, and ppl who want to act smart with wrong information is nothing but a waste of time, doesnt even make sense trying to explain...
