my vote would be to go to the category.
It seems to be more of just a sample picture for the category.
On a side note, I kind of miss the category links on the main page. Just from my perspective, what is more important to put on the main page
1. Recent changes / featured people
2. links to the product categories
How about on the main page, removing the reccent changes/featured people lists and replacing them with the same category list that appears on http://www.productwiki.com/products/ (right panel) ?
