Firstly, thanks for this place to post for newbies.
Secondly, I have read TPB, Architect, QV(reading), Phoebus Krumm, Timepeeper and have found all of them to be really enjoyable. For comparison, I'd like to add that I have read only classics like Asimov, Heinlein, Larry Niven, etc and I find many of these of the same entertainment level, although a bit modern and local (US centred)
Thirdly, the artwork is brilliant. There are several other webcomics that arent as good at the art - so this one stands out.
I'm not a great fanboy of novels as such (Star Trek, Star Wars are another matter
) so I only read once or maybe occasionally the second time. In my opinion, great scifi is that which brings forth unexpected concepts and thinking. Quantum Vibe has a good helping of that and also some well-thought out futuristic technology ideas.
I'd love to contribute any ideas to plots or concepts if that helps because I cannot afford to purchase the books.
Good luck and great stuff!
