Recomendations for a new camera?

Ok, so im saving up for a new camera but i have no idea what kind to get. I was thinking a Nikon, but i dont know, comparatively speaking, what companies make the best cameras. Most of the pictures that i take are close-ups, dont know if that makes any diffrence. I know that cameras are expensive, but i would prefer one in the $200-350 price range, but nothing above $700. If there are any pro-photographers out there that have any input i'm all for it.

Why are the quality on my tumblr photos worse if I enlarge them in the html?

I have that 'Catching Elephant' on my tumblr as my theme, and I tried to make the photos a bit larger by editing the html, but then the quality of the pictures turned really bad. And they're not usually low quality photos, they're taken with a Nikon camera, and the pixels are usually around 3800x2800 (ca), which is why I don't understand why they look so bad now, just because I enlarged them a bit. Please help, it'd be very much appreciated!
