In my opinion, VSL should put some time in reworking their website. As a new user you doesn't find the important information on the product pages, I had to search the entire (!) forum. Also, I think the main benefits (USPs) should be more prominent and on every single product page.
But what's important to you others may care less about. Comparitvely speaking I think VSL's product pages are comprable to their competitors. Personally, I go straight to the demos and if I like what I hear I'll dig deeper.
It's a tough job trying to design product pages for these libraries because you're dealing with a wide variety of people. Some people are old fashion pen and paper composers who just want their written works realized and could care less about how many samples a library has to offer or mic positions etc. But they might care a lot about the fact that a professional musician like Gisela Mashayekhi-Beer recorded the flute samples on the Woodwinds I library. While others may have more of a technical background in computers/programming and care more about GUI's Interfaces, software ease of use, and wouldn't know the difference between Gisela Mashayekhi-Beer and Gisela Mashayekhi-Grape Juice.
Then there are media composers who are interested more in the number of articulations so they can quickly create their mockups for clients. These folks could care less about the MIDI controllers and sample manipulation (VI Pro) because they're just trying to create an approximation of something that will be recorded live.
Then you have hobbyists, educators, students etc. Everybody has different needs.
