I call myself a software developer, and I even did work on a frontend application for Steem.
It gets my goat too. All that needs to happen is that any of these big frontends implements end to end memo encryption, as was intended by the inclusion of a memo keypair.
It baffles me that this one simple implementation hasn't been done, and you can bet that if I release a frontend there will certainly be encrypted transfer memos.
That alone could be used as basically instant messaging with how quick block times are around here. So much utility could be had, and I'm sure the crowd would enjoy and use it.
It's been years, and still we basically don't use those memo keys for anything. There's been dozens of hardforks, but still no encrypted memos! It's a shame.
