Clapperhead has a point.  There is an opportunity or two here, possibly huge ones.

The wallet in my pocket never gets forked.  If my bank was ever "on the wrong fork" so to speak, there would be hell to pay.  But in the crypto-community, this is normal.  Pretty much every coin has had fork issues at some point.  You can blame bad guys and you can blame people who don't update the wallet, and you can blame 51% attacks, but the problem is the blockchain system allows forks.  I don't know the answer to this, but this needs to get fixed or cryptocurrency will never get any real acceptance.  Sure, there are a lot of people mining and a lot of people trading.  It's a tiny niche.  There are a million times as many people safely doing online banking every day without any fear of having their bank get forked.

And about wallet updates, it's normal for wallet updates to get released without really alerting people about the updates.  Sure, you post here and maybe some other places, but there is no alert that there is any issue.  I've got 20 wallets.  I don't check the posts for them all every day, it would take too long.  I don't even check them all every week, just the ones that have issues, have pending updates I know about, and a handful that are either hot or in trouble.  Some of them I never check.  The last time I checked the bitcoin thread or their website was when they released a new wallet.  The time before that was like a year ago.  I haven't looked at the Litecoin thread in like 2 years.

Sometimes those wallet updates will result in lost coins if not acted on promptly.  People lost Rubies when Ruby switched to POS.  If you didn't update by a certain date, you were out of luck.  I think the same happened with the Saturncoin to Saturncoin2 migration.  Granted, these are isolated cases involving hard forks, but if a person just had some coins in there wallet and wasn't actively involved with those coins, they were just out of luck.  They lost their coins.  That would not be acceptable at a bank.

I've seen wallets post messages.  I think about two months ago, the Zeitcoin wallet started giving me a message every time I started it about a Zeit-Knight event where new Zeit Knights would be anounced.  And there was an update.  That worked out great.  I updated my wallet.  Apparently a month ago, there was another update, but no message this time.  I only know about it right now because I just checked the thread to get a date for when the Zeit-Knight thing happened.  Ooops.  I guess I'll be updating that wallet.  Knowing that they have messaging technology, why the hell wouldn't they use it?

I think the real question is why doesn't every coin dev team use messaging technology to send messages directly to peoples wallets so they really have no excuse not to update?

So there are two possible enhancements that would help Diamond differentiate from all the other coins and possibly gain some traction as a form of currency that regular people might feel comfortable about using.  The messaging update is probably simple.  The code already exists, it just needs to be implemented and used regularly.
