I am, typically, neither rude nor stupid.
I am also typically surrounded by people who care very little about startups, software, and the like. So when I'm around other people who care about software, startups, and the like, I tend to mention our point of commonality a bit. The one I bring up most often is my own because a) I'm intimately acquainted with it and b) unlike my day job, I can talk about it without getting fired if I say too much.
But I try to be a good citizen here. You may feel that I mention my software in almost every post. Memory plays funny tricks with us. I don't trust mine with anything important, so I checked with the indispensable external memory of searchyc.com, and it turns out that I've mentioned it about 18 times in the last 255 comments, which is about 7% or so. (Throw another 6 on the tally for other people referring to my software, if you care to.) Now I might be counting wrong, as I suck at it almost as bad as I do at remembering things, but I don't suck quite so badly that 7% is "almost every post".
(Sidenote: this is my 256th comment? There should be a geekiversary for that.)
Now I do try to keep my contributions to the community worth having me here. If you are to believe the last ~1800 ish times people pushed the "More comments like this one please!" button, I like to think I'm doing a halfway decent job. But I'll try to recalibrate due to your feedback.
Say, what would it take to get you behind the controls of your very own gliding duck?
Maybe just 7% of your comments are about your business, but imagine you are talking to a mattress salesman, and every 10th sentences he says is about mattresses or about his business. Is that not a bit annoying?
I'm not saying what you are doing is wrong or that it does not fit the standards of the community. I'm just saying it annoys me personally. Nobody else maybe, just me. So I'm pointing it out to you, because it may also be annoying someone else, and if nobody mentions it, you won't be aware of this.
For example, you original comment on this thread was funny and insightful. The followup comment about bingo software was not, it just seemed like marketing.
