A couple of years after dot.com many of us here migrated to online Mirc chat; were 10-15 dedicated traders posting trades in a room of about 20. Stocks outside top 200 was forbidden. That was a great platform - sure there was alot of frivolity - bull bear battles and what not but thats the market its' full of opinions. Some heavy hitters back in the day was in that chat - I know because I was moderator
Traders there were declaring buys and sells in real time. Then Twitter came along and everyone migrated there. Twitter is a platform for academics voicing their opinions not really ideal for traders. Way too much clutter.
