I'm doing a project that I'll possibly be documenting quite well, and need your opinions on one thing. So, which one is more usual in modern computers, serial or parallel port? I'm asking this because I'm trying to make my project easy to replicate by others, without the need of any kind of USB-to-serial converters or whatever.
You could check your own computers and check out what ports (parallel, serial) does it have.

serial ports on computers are male... not female, so you are likely looking at a monitor port or have manufacturing issues they are both getting harder to find STOCK on a computer, but you can always get a very cheap addon card, PCI/PCI-E for desktops and expresscard for laptops
many people still have desktops that have at least one of them, usually both...

Serial is the most common I think, and you're more likely to find a laptop with a serial than parallel port. Parallel is outdated and used for nothing but hobbyist projects anymore, while you still find odds and ends which work with serial, although even it is becoming outdated. However, every one of my stationary computers so far has had both a parallel and serial port, so they're not entirely obsolete yet. My latest stationary was built just a few months ago.

Well, if you are working on something usefull many people would need you probably should take in account the fact that many modern desktop PCs and all the modern laptops lack any ports but USB. However most motherboards (every single one I saw, in fact) still have pins for additional LPT and COM ports (I had some experience both finding the sorresponding output cables and making ones myself, but for those who use prebuilt PCs that may void the warranty, also the laptop users will be forced to get additional convertors) so it will not be much of a problem otherwise.

Can u figure out a way to use USB.
Yes, using USB is possible, but it would make the project more complicated. At this point I reveal that the project will have a AVR microcontroller as its brain. To program it via USB, I would need to build a USB programmer which includes another AVR microcontroller. That would need to be programmed with another programmer, so I think it's not worth it.

I'd go for serial. You can always use one of those FT232 chips to make it work with USB too.
that's always a solution for using USB... you can even get CABLES with that chip installed that take USB and bring it down to serial for microcontrollers, or you can get the chips on a breakout board, or breadboard modules, and they are cheap too!

Parallel or serial port?
