It seems that the devs have jumped ship:
The first post and the website is outdated since weeks, it does not take hours to update...
And every time they reply, there is always promises but in the end nothing happens.
For example:
Klondike Coin Promotional Video - Currently in development and should be released within the next week
can we see something of it ?
And explorer.klondikecoin.com is down again...
Maybe you shuld jump so better people can hold the KDC

I think he's raised a genuine concern here without trolling, so let's not be too hasty with the suggestions to dump

.
As said, we all have day jobs and families along with our commitments to KDC. My response to your point about the video would be - would you rather have a promotional video or a site where you can actually trade your KDC? We've been working hard to get the game key site live, so it's been about prioritising.
I'm not part of the dev team, but I speak with them daily and can assure you the coin hasn't been abandoned. But yeah, patience, we're working hard! I'll let them know about the block explorer.
