This has been out in the wild for a while now. From the jump, I want to be very clear -- we should be careful to not reveal any IC specifics about what it currently does / does not reveal past what Slither's initial post mentions, though the current implementation as I understand it at least doesn't quite reflect what was mentioned, either. Nor should we mention obviously how it's accessed, etc. -- this is IC info for a reason. I'm sure myself and others who've interacted with the mechanic are more than happy if asked to talk in more detail with staff if they wanted more detailed feedback in private, but that said --
As currently implemented, the decker chatter information is very underwhelming. A tweak could be made to the price one needs to invest which would be a nice change, but even then, profiting from brokering the info gained is very very difficult, because the information one can get is generally not particularly valuable, except in very specific hit-or-miss cases, pure luck and timing, and knowing someone who knows someone who might be the single person interested in knowing about a particular transaction. By and large the information just isn't worth paying for, and isn't worth the other factors involved in attaining it.
Not only does this just 'Feel Bad' as a player engaging with a game mechanic, it feels unthemely. My personal vision for the archetype surely might different from anyone else's or the staff's vision for them in this game, but deckers in cyberpunk have always felt like they should be the ultimate data hounds, the ones you're the most paranoid about -- possibly behind every camera when you're doing something you want forgotten, rifling through your bank account transfers, your emails, listening to your phone calls, snooping on your encrypted SIC traffic....not all of it all the time of course, but that edge of paranoia should always be there. You can beat the shit out the decker probably, but you should be worried about what data of yours they're going to break in and sell off afterward if they're good at what they do.
For them to have such a sort of 'meh' and pricey chatter pipeline feels counter to theme and I feel like every decker I've known more or less ignores it unless they have a niche circumstance.
Without offering specifics, there are a number of interesting tweaks that would give more value / leverage to those accessing the information and make those putting complete trust in the systems holding their finances safe and private a bit more paranoid, both of which would be good for the game, I think.
