Hi,
such a graphically rather simple banner image should never have 40+kb! Here the results of proper compression thru Fireworks (Adobe Photoshop or free software achieve similar results) as gif and a middle quality jpg:

7kb gif – https://img71.imageshack.us/img71/8628/popbanner4ps.gif
Even with graphics intense banners of larger size I rarely reach more than 25kb. Many, MANY people still access the internet on a modem. If a page takes ages to load already regarding graphics they wander on before you page is visible.
I guess you tried to go for a “fresh” and easy look with a dark background. However I too think that this white/yellow on black is a tad too hefty. Take the edge off the black a bit (dark anthrazite or dark blue also are dark, but not that unremitting) or go for a milder yellow (= one more into the red range like corn or wheat yellow instead of this bright citrus kadmium one) and a broken (= eggshell or greyish) white.
If you have 3 columns, USE them!
You put all the links left and have little on the right. Depending on whether or not you need your advertisements (I’d quickly lose them) try for a format less invasive and place some content instead on the right column. E.g. place all the “non-blog” links on the right, or do it vice versa.
Coming with this advice is the other that maybe you should shed a bit of the “clutter”, there are countless off site links which could just as well go into a links page instead, or you could make several links pages linking only what you currently have as headings on the columns themselves.
I agree with this “too wide” impression, wide and stretchy works better for different types of design. Give the user a bit of space where to rest his eyes, give them a bit of a margin/padding with nothing, like the page of a book.
Too many posts are visible as well, try doing only 5 or only 10 teasers mostly then without the photos (or make them clickable thumbnails).
But, all put together it’s not truly bad, the concrete idea and line are there, which is actually most important.
