Google developer Dan Holevoet published the roadmap for the forthcoming changes to the iGoogle personalized home page. You can check out the presentation here.
The site, which anecdotally I can tell you is getting very popular, will get a new canvas view (below) starting in June and social features over the summer. However, what's most notable is that iGoogle is getting ads. They have not shown yet what this will look like visually. However, there is more info posted in an official FAQ.
According to the Google deck and FAQ, ads will appear embedded in the widgets themselves and only in the new canvas view - offering developers a way to monetize. In addition, Google will solicit feedback from users as they go. However, I wonder if this is going to add to the clutter of the site. Further, I would be interested if the developers use Open Social features to make the ads as social as the widgets promise to become.
Meanwhile in related news, Google Reader is closing in on Bloglines, according to new data from Hitwise. The site is currently free of ads but with Google's purchase of Feedburner I wonder if a Gmail-like model is in the works for this site too - particularly as its use increases. Ideally this would encourage feed owners to join Feedburner's ad networks and share in the monetization in and Adsense like model.
