For anyone using the software for the first time, the 'addnodes' entries in the announcement post are long gone.
Current nodes are available here: https://nyan.space/peers.php if required
however it will work without adding anything manually, valid nodes will be obtained from DNS as with most other coins.

PoS is gone.

Although the original poll was in favour of it, it had a very small number of votes and therefore lacked in credibility.
Someone did apparently create a PoS version, but that was started well over a year ago, no code was ever published and nothing has been said or heard about it since 2014.
A poll elsewhere supported a change to X11 - again with very few votes and that never happened either.

Without the support of the majority (probably 90%+), any such change is doomed.   If some change and others do not, the result will be two separate chains, total confusion and the end of the world as we know it.
