I don't think he was "accusing" you of not having a financial interest.
Personally, when I used to post on stock boards, I'd sometimes post on boards in which I had no financial interest but because of my experience felt my input from a different perspective (say, as a software guy, or as someone who'd seen an identical situation previously) could be beneficial to the group.
I've never considered a financial interest to be any kind of requirement for talking about a company. And I can't help but label anyone a "twit" (in my own mind, of course) who posts "Why are you posting about this stock if you're not a shareholder?"
There's a widespread misconception that market-talk message boards should be online meeting places for shareholders. Definitely not the case. At least not in any board that would be worth its weight in servers.
If I encounter a lot of people saying that Hyundai's are the best cars made and everyone should own one, I'm very likely to weigh in as a former mechanic and say "I've worked on Korean cars and a common theme with them is spot-welds where full welds should be used and using only 'enough' fasteners and of barely sufficient size to hold a part in place rather than going a bit farther than is necessary, like any Toyota does."
And that opinion would be valuable, whether I've owned a Hyundai or not.
There's probably a place for "shareholder clubs" on the internet somewhere. I just don't know where that place is. Until someone figures it out and implements it (for a fee, which few would be willing to pay, so self-sufficiency of such a site would be a challenge), all that's out there is the current crop of message boards, none of which (as far as I know) specifically cater only to shareholders.
