In my personal experience a newbie should not start posting immediately, instead he should first select a topic, and read more indept about it make some genuine efforts to google if something is not clear. I believe they should stop hiding behind the veil of language barrier, many of them are not proficient in English, so my advice is stick to local forums, make use of online translators, read how people are making well constructed statements and then begin to post. Another major issue with newbies I observe is FOMO, if they don't post enough they'll never get merits, or be able to wear signatures to earn extra income it's about time they learn it's quality that matters here not quantity.
