But, some people can't (compliance, or we don't support their broker yet), others don't want to, which is fine too.
Whilst Commonstock is a 'tool', its also a community, a place to share research, ask questions, and make connections. Connected brokerage is not compulsory for that.
I don't have a brokerage connected (not supported), but I share research, find research, have thoughtful conversations, etc.
