Last year I wanted to experiment with what I called "Poor Man's E-Mail," and it sounds exactly like what you're suggesting with the memo field for sending 0.001 HBD to a recipient. In my case I was going to send 0.001 Ecency Points since I didn't want people to worry about using money. I couldn't find volunteers to help me test Poor Man's E-Mail, so the experiment died.
For short messages this could work. For short content such as a buzz this could work. Longer than that size, I can't say.

Experiment being the key word.
We already know that a message could be sent easily. It is already there each time we hit the send button. How many characters can be placed in a memo I do not know. It seems to be a lot.
My guess is the possibilities to this revolve around the front end tying into the data posted to the chain. It is a matter of filtering it and aligning it in the application's layout.
Not sure anyone has the interest in that per se. It is an interesting thought experiment. If it is technically possible, it would be interested to see it incorporated into something like Leofinance to see how it works and was received.

A dApp would be best to properly display the message. As it is, it can be viewed in the same was as notifications we get when we receive daily drips of HIVE or other tokens.
Also, it would be the same 0.001 HBD/LEO/HIVE/Ecency Points/etc. bouncing back and forth between message recipients.
The Memo Key would be essential if we want to employ privacy measures. The other day I thought I saw a post with an image of such a message sent by @asphamilton, although I don't know how he was able to make his message private.
