I have to say that when this website redesign started I was very skeptical, especially after the first Beta version, which was horrendous. However, after these subsequent revisions, the website has come a long way. Even after Beta 2, I preferred the original home page, but Beta 3 is now the one I like best.
Why the change? First, Tom's listened to its users, changing the layout, adding links (rather than a drop-down) to get to the different categories of latest articles, adding more stories per page to the latest news section, and (I think) adding more entries to the forum feed. The charts have been rearranged by everyone in the forums, but they are eminently accessible in a readable row at the bottom now, a very easy location to find.
Second, the new layout is clean. Information is accessible. News and the forums are prominently displayed. Yes it is a drastic change from the original, which displayed a TON of information because of the various "sections" on different aspects of computing (GPU/CPU/Storage etc). However, the SAME information is present on the new page, despite being much smaller (shorter? cleaner?) because instead of being spread out all over the page (tons of scrolling) it is now accessible through a single click, which DYNAMICALLY changes the home page. Being able to click on each category and get an instant display of those articles is key for me. The layout for all sections is now the same because they use the same "Latest Articles" box which makes scanning much easier for me. And if I don't want to look at graphics articles today, i don't have to click on it and can just skip over it.
Overall I think Beta 3 is great effort by Tom's, and you have at least one reader who will no longer be disgruntled if the latest Beta becomes the final release.
