Online Previews: Ionization?

Painting - Ran Ortner

Ionization: Process by which Ions - or atoms only having either a net positive or negative electric charge are created.

Generously (or not) assuming that both digitized and digital products come to hierarchically hold all information that's usually packaged as ratings in their presentation:
Besides description, when a preview is the only form of information for a virtual item that can be obtained - through transaction - what tools could forestall remorse?

Given the qualities of a preview being (i) cyclical/redundant, (ii) unique, and (iii) incomplete. Can patience be the trust metric?
A problem being it's often conditionally deemed thriftless.

An estimated time of response or date an offering is posted often imbue one with a large sense of uncertainty. Whether the author has or not read a potential buyer's interest, forgot to remove the listing, neglected the platform or has too many email addresses etc. render progress inconclusive from the other user's screen. Waiting for an answer is barren if the decision to not answer provides no evidence of itself to the other. While possible to argue a person would continue writing until their interest is reciprocated, until then it's a waste of time, bandwidth, tolerance, and energy. "Online" isn't a guarantee of attendance. It's necessary but insufficient.
Likewise, registering disinterest has no incentives - it seems easier to not answer instead of writing/notifying the recipient, from a seller's lens.

Would an integrative 'timestamp' application lend a hand? Just a few colors to indicate:

  • If time of response is still the same as at the time of posting (from seller). And what is the ratio of registered interest and response (from potential service or product buyer)
  • If disinterest - where a right, is promptly registered and neutrally imparted (whether before or after interaction can be logged).
  • Response performance from both ends (buyer/seller) is present across several platforms, so as to measure this against transaction success.

Couldn't less time be wasted over dubiety? Wouldn't previews offer more behalf and pilotage?
Wouldn't steps preluding exchange become equally valuable?
(e.g. Person H both responds and transacts with a parity of K%, seller J responds and transacts with a parity of K%. Not responding lowers both if dealing with someone of better ratios, responding and not transacting lowers one. Responding and transacting increases both).
