Also, by removing the menu from the home page and not replacing it with anything signposting the same content on the site, again it's not "highlighting exactly the same suite of content as the previous home page - just more succinctly"
This is not about the blocks of content.
This is about the first view you get as a new user to the site. With the slider at the top, many people will never see the blocks.
Have a look at this picture - that's what I see when I look at the home page.
Before, you could see what the site was about, now people will have much less of an idea. We all know what mumsnet is. But the new homepage likely fails the "what is this website about" test IMO.
People will be able to guess it's about being a mum, of course. But will they get a feel for what the site is for? Will they know that it's a discussion forum?
It looks very Daily Mail to me.
Before, the words I saw included "talk, work, pregnancy, baby, child, work, style and beauty, education, money, food"
I knew what the site was about, and it seemed to be abotut important (to me) and relevant topics
Now I see:
"Clairol"
"Are you calling my baby fat"
"What gives you irrational rage"
"The woman in the Top Cat Halifax mortgage advert"
"To ask what bonny means when describing a baby"
"Have I made the right choice between two girls"
"Nice & Easy Clairol"
"Colour so natural looking"
"Try it now"
Can you see how the effect of this is dumbing down the site? People new to the site won't know those titles are discussions, necessarily. They could be gossipy articles. In fact the whole site looks a lot more gossipy and less trustworthy than it used to.
I would recommend doing a simple 5 second test with both the old home page and the new page and asking people who are not familiar with mumsnet, but who are your target audience - "what do you think this site is about", "what do you think people do on this site" and "do you think this is a website that you would like?"
If my suspicions are correct you might be surprised at how different the results are and how much better people were able to guess what the website was about with the old page.
