Ok, I hate you for making this thread FOR THE FOLLOWING REASONS
One, you're website isn't even remotely 8-bit, it just looks like any number of pieces of junk from geocities.
Two, the layout is absolutely primitive, not only is it hideously painful to use, it's just outdated and ugly. That's not being retro, that's being lazy.
That's really it, but if you want me to be ~*constructive*~ allow me to expand.
If you want to do something really 8-bit or resembling an NES or even something like the C64, you're going to need to work at it, not just make it bare. The thing is, internet primitive, and serious primitive hardware are entirely different things. What you have now, is essentially just primitive code. If you want it to have that 8-bit look take a page from the new Blip Fest website. It doesn't look like it's being run on an old system but it has the aesthetic, or that kind of thing, which is really the best you're going to be able to do while still viewing the website on modern hardware.
If you want it to really feel like an old computer/game system, you're going to need to put some real work into it and make something that gives that kind of feel not only in the way it looks but in the way you use it. For example, the website http://chiptune.com/ basically has a recreation of the amiga workbench on that functions as the website. Your layout on the other hand, is a few columns, one for navigation and ads, one for page content, and another one for ads. The biggest issue is really your content area, it's not well defined and is made up entirely of awkwardly long paragraphs. Having a more well defined text area would just be nicer to read. Also the graphics on your site don't really seem to have much significance, the background is some weird diagonal tiled brick thing, which looks as though it was intended to be pixelated, but... it's diagonal, and then the banner has those music notes which, while not anti-aliased, still aren't the big blockey pixel style type things that would evoke and 8-bit look and feel. The same goes for the background of the banner, the sizes are weird, and you might want to look into the palette of your site, if you want it to look more 8-bit, try using an NES color palette.
Now, you said you liked the way it looks outdated. If you want to go for the ye olde internette look, yes your site wins, just throw in a few animated gifs of spinning musical notes and have one of those annoying auto-playing midi embeds. but really you're neither here nor there. You need to decide whether you want to look 8-bit, or whether you want to look old internet, you can't do both without just looking inept, so your best bet is to pick one and go with it. Personally I would say, oh just fuck it, make a modern website, it's a modern technology, don't try to make it something that it isn't, but you won't listen to that so i'd say go with 8bit, because then you might at least have some hope of making it useable. Just use some proper CSS please. It helps.
Also one more thing, about the ads, you can't really honestly expect anyone who doesn't want to look at stupid ads for random bullshit to use firefox adblocker. really it's almost criminal to expect people to use firefox. Chances are you're not really gonna make too much money off of that, and if you want anyone to take your site seriously at all having ads is not going to help. if you feel you positively must at least just go with some simple google text ads, because seriously, I got an ad for sexy russian chicks or something, that doesn't make me think your website is really a great palce to hang around.
