Nope. Why should we replace a discussion thread with a Wiki page???
Both serve different needs. And both are needed. And here’s a different perspective on why sometimes “old is gold” 
1.The stock discussions are unstructured - because thats how discussions tend to me. But it records for posterity how the story unravels - events happen, members react, some panic and leave the bandwagon, others reason it out and stay the course (through ignorables) make their way to say an Ajanta Pharma’s 65x multibagger in 5 years. Academia are fascinated - actually some are actively compiling and tabulating the journey of investor behaviour that is captured in these threads Sir …there is a wealth of insights on how decisions are made, behavioural investing, ability to decide on the odds, the choices that are available at each fork in the story - in many of these storied journeys in an Astral, Mayur, Ajanta, Shilpa, Polymed, Kaveri, Amara Raja, Shriram City, PI industries and many many more

You will be hacked up…if anyone even tries to clean up storied threads …yes, many threads which do not see quality participation/discussion which get junk accumulated are a different beast…even they will have lessons to teach on what not to do, and more…
Have you folks not seen the Showcase discussion threads at the Home Page!!
2.In parallel there is also a distinct need for structured pieces …where you can come to grips on the essentials of a business in just 15-20 minutes …through a crisp note like a stock Story - what does it have - What are the Products, who are the customers, what are the bullish arguments, what are the bearish arguments, what are the interesting optionalities …thats it … a simple concise story. Thrown in Peer comparison of a certain rigour and this becomes a real “living” document that can be kept updated.
Instead of opining what could be done, we would like folks like you to say - Hey I want to write a stock story for my favourite business say Cupid, or XYZ, write that up in 15 days or 30 days. Upload it here for Seniors to see if you have the ability, and the serious of intent to doa complete job - someone who can look at both sides of the coin and come up with a balanced piece.
Nothing verbose - not 10 pages. Just 1 page!!
Can you do that??
How many will volunteer to do that??
Lets watch this space…including your seriousness of intent
