I have to wonder if you're trying to address people who whine about these things or the people who are just straight out trying to inform people because they are living it every day, there is a difference.
Photography full time is NOT easy but everyone thinks it is, they think it's good and easy money because they don't think about the actual cost of business, they think there's no stress because when they take a photo there is none, and yes everyone who ever took a photo and mom/dad/friend said it was great does think they could be a pro. It's how it is and does not happen in too many other professions, some yes.
Personally, the whiners I can understand being annoyed by because you do what you have to do to adjust and survive in this industry (any business for that matter). In most cases you can whine about something or do something about it! However, any full timer who has not let out a b**ch here and there about this and that going on is probably lying.
However, for those trying to just inform and educate - maybe a little harsh at times - it's not a bad thing. For every person (because it's non-pros to) who puts the info about how hard it is in this industry on this and other boards there's 50 posts about how easy it is from people that are uneducated in the field and get offended when you point out anything they don't want to hear. Hell, even Yahoo and USA Today had articles about how easy it is to make money as a photographer leaving out very important info on the people they profiled. I'm the first to admit I'm very straight forward, screw the sugar coating, here's how it is - deal with it or you won't survive mentality (try playing for one of the teams I coach!!)
As someone who started out as a hobbyists with no ambition to do it as a career to now doing it full time going through each stage things are a lot easier when you're getting a check here and there instead of doing it full time. You'd be amazed at the difference to tell you the truth. Also, you don't always get to make the call when clients are involved, and it's not always an adventure. It's a fun job to have, but it's still a business and needs to be run like one. There's times you hate it but they are heavily outweighed by the times you love it in most cases - and if not, then it's not the career for you. There are thousands of people who fail every year trying to be photogs just because they loved it as a hobby and hate it as a job. So it is what it is...
Technology aspect - either embrace it or die is pretty much it unless you can pull off a fire sale, but I warn you Bruce Willis will stop you!
