I didn't ask for your credentials, and neither do I care. I don't wish to argue anything. I'm merely stating that your comment came across abrupt, assumptive and quite frankly unprofessional. No better than "the kid online". You're not helping yourself with that last post either.
Websites like this should not be run by angry fanboys or "IT Pros" who don't know how to communicate properly, or represent a product/service. As an Administrator, I would expect a more formal and friendly approach.
But hey, what do I know? I'm just a consumer...
There's no problem with people chiming in with their field of expertise. Perhaps he was coming off as bragging or pushing his job experience in a needless way. He said his 10 cents and talked about what he thinks is relevant or soon to be relevant in this industry. You don't have to agree with it. Sounds like someone is jealous of said credentials.
