The problem I have with this #talkpay thing is that it assumes everyone I connect with is in our lucrative echo chamber. I'd feel like a asshole talking about my income as a contract developer knowing I have followers who are really struggling to find work / decent pay outside of technology.
Conferences, tech meetups etc I'm usually the first to be championing developer solidarity and pushing the message that we can and should all be demanding more money, everywhere else I try and keep it low profile to not rub peoples noses in it.
I have a lot of non-tech folks ask me about money (when they ask me what I do and if it pays well) and I always try to avoid giving numbers and go with a more generic 'I can't complain, things are ok/good'. I earn a lot (and I mean a lot) compared to non-tech folks where I live: 20x difference in some cases. I had a friend recently in a conversation mentioning that buying X (one of those cheap android tablets for kids) as a birthday present was 3 days worth of her work. In my case, it is less than 1.5 hours of my work.
I'm very happy for earning these values, and I try to give back when I can, pick up the bill here and there (enough to help, but not enough for people to resent it) but I know we developers are quite lucky with the luck of the draw we got in this little slice of time and IMO, we should be more considerate of others in these cases.
I feel the same way as a 2012 college graduate. Most of my college friends are still unemployed or working in marginal work (temps, office admins, phone support). On top of that, most are buried in student loans (private college) whereas I had parents able to pick up the tab. More than one has turned to webcam porn to make money while I'm charging $$$ as a software contractor.
I post photos on Facebook from Tokyo or Berlin and sometimes wonder if I'm pissing off my friends.
I don't think you should stop posting photos from your trips just because you are 'afraid' you will be pissing off your friends. They can always unfollow you (or whatever FB allows you to do, I'm not big on social networks) if they find it 'offensive'. I just think it is a balancing act between sharing parts of your life, and sharing absolute numbers or boasting.
Anyone that knows me for more than 5 minutes, knows I'm doing well (I live in a nice place, in a very expensive area for example and I don't hide this), but at the same time, I avoid letting (outside of very close friends) people know how well exactly. I never talk about money or salaries or what not. That doesn't mean I won't invite them over for dinner/a swim in the pool just in case I 'piss them off'.
