For anyone with the Galaxy Nexus here, I'd like to point you in the direction of the pressureNET (https://market.android.com/details?id=ca.cumulonimbus.barome...) as you are in a new group of Android users that have barometers! I'm the author of this app, and we're building a crowd-sourced network of live-updating Android barometers in hopes that we can improve short-term weather prediction. The app is open source and free, of course! You can get the code at cumulonimbus.ca

Edit: Most of our users are on the Xoom (and some other tablets). I have not been able to test on the Galaxy Nexus yet. If you have bug reports, please send them to software@cumulonimbus.ca
So, I was nervous of that but decided to post anyway. I think HN seems okay with this post (it currently has 9 points, for full disclosure) but if this type of post isn't welcome here, I will take it down. I'm not profiting off this and the project is entirely open source, so I felt okay about it. Does HN want it deleted?
In my opinion, it was dman's post that was in poor taste. Hacker news is and should be about people showing off their hacks. Additionally his post adds no content -- a simple click on the downvote button provides all the information and feedback required.
I only kept my post brief to be polite. While I agree that Hacker News is the place to show off hacks hijacking threads is not the way to do it. If parent poster has a hack that is worth showing on HN he should submit it as a news item and if there is intrinsic merit the post will attract an audience. Posting self promotional information on threads that are tangentially related is in poor taste in my opinion. Its a slippery slope - if every iphone post here attracted comments by all of us who were building an iphone app then HN would be the worse for it.
If he was pushing a random android app on an article that was about a random android phone then you would have a good point. In this case it is more than just tangentially related, the vast majority (read: pretty much all) android phones don't have barometers, this is pretty much the only phone that can even run it. And it also answers the question of "what would I ever do with a barometer on my phone?".
I think the post was relevant. I don't mind self-promotion if the thing being promoted has hack value.

Re dsman's comment: "... if every iphone post here attracted comments by all of us who were building an iphone app then HN would be the worse for it"
It depends, IMO, on the nature of the app. Trying to crowdsource weather prediction is a sufficiently interesting hack that I think HN would very much not be the worse for knowing about this. I would only find it objectionable if cryptoz starts promoting in every Galaxy Nexus thread.
