These are my thoughts:
1. The changes to the front page are awesome, generally speaking.
2. The thumbnail front-cover images do clutter the page a bit, but I think it's correct to have them there. As aspiring/consolidated writers we must start our marketing right from the very workshop process. A good cover is a must, even if it's only for this site.
3. The part showing our connections' bookshelves might be bit too much. I would suggest to put a button which takes you to another page where the bookshelves are shown rather than to clutter the front page even more.
4. The "Articles" and "Essays" part needs to be reduced to the last 5. It's not that people post articles and essays that frequently. BTW, in the case of articles and essays, I would eliminate the book cover thumbnail. Since they are not books, it's unlikely that there would ever exist a book cover for them, even if they are published. For those arguing that the same might be valid for poems and short stories--which are typically published as anthologies--I would answer that many of them do come with illustrations particular to the poem or short story within the anthology. The latter is seldom valid for essays, even the published ones. Articles... well, if they end up in magazines, many times there's an illustration, but it all depends on the article and the magazine. Anyway, I'd eliminate the thumbnail images for Articles and Essays looking forward to uncluttering the front page.
5. Connections didn't exist in the previous site. However, I'm sure that many of us developed some practical way to check whether the people we reciprocated with had published anything new. So, I wouldn't say that a front-page section showing what our connections have published recently is discouraging the reviewal of material posted by newbies.
6. The above said, I'm in favour or providing extra points to anything published by new member under 3 months. Also, I'd suggest to create a new section on top of the page (right below "New Writing to Review from Your Groups") showing the latest 5 works published by members under 3 months, despite whether they are novels, short stories, poems, essays, or articles. All this would increase the attention provided to newbies.
7. A good idea might be that, once a new person signs in, a sort of wizard pops up asking her whether she wants to post in the Premium forum introducing herself. The wizard can guide the newbie who can fill the blanks with her name/pen name, genre, preferred reading, published works (if any) and stuff of the sort about her literary preferences. Blank extra space for personal, optional info could exist too. In the previous site, those newbies who introduced themselves in the "New members" forum often received more reviews than those who didn't.
