You are right - there is no need for "Posting" - if you know everything about the business.
One posts to invite views and critique - to get to know the GAPS in one's effort, learning and investment refinement.
No one at VP is an Expert. All of us are Learners in this game - from folks smarter, better, more refined at the Investment ART than us. Please realise we allow everyone to post - even a newbie - because we feel everyone can add value. We do not insist on the thread INITIATING post as a PHD on the stock. But yes, we insist on some basic guidelines being met.
So, it is not about ability. It is about the EFFORT. And, It is about the ATTITUDE.
If anyone examines the above exchange impartially, you cannot help notice:
- When someone points out the gaps in the effort, there is no constructive effort to take it forward from there
- If you are the thread/idea initiator (you are not someone just posting a reply) and your "real" objective is to learn from the feedback, and understand what you have missed in your analysis/effort, surely you will react differently - than what was at evidence in this thread
- Instead, an attempt is made to gloss over the objections and underplay the Risks by referring to "Growth" !!
- Worse, there is IRRESPONSIBLE (speculative) reference to Transient Multibaggers and such hype to justify/condone the lack of serious examination/digging
Moderator interventions are completely ignored. Admin intervention is brushed off with a brusque "delete it if you like". As HIteshbhai has commented somewhere else, such folks display this couldn't care less bravado, do not identify with VP ethos/culture, and seem to think that they are doing VP a favour by posting here, really??
Witness this last line.
In anyway myself/many old timers have almost stopped posting in VP 
Doesn't it tell all about the lack of identification with everything that is cherished at VP?
