And philosophically, think about the kind of poster to whom streaming, or even delayed, quotes, are important as they read and write messages.
I was nodding in agreement until I reached that part.
Traders or people to whom the prices of equities are meaningful are not "undesirable" or "inferior".
To give another example of where I found delayed quotes to be handy, I checked out a few threads on this morning. One that was brought up in a conversation on SI and a couple that I checked out of curiosity. In each instance, I was glad to see the quotes right there rather than having to fetch them from elsewhere. Not "I love this so much I'll pay good money for it" glad; but glad nonetheless. It was convenient.
