The default Pageflakes page has a dozen "flakes" or predefined containers for content:
1. Local Weather
2. Local News
3. "Pageflakes Central"
4. Local Flickr photos
5. Video feeds
6. "Mother of all Podcast feeds"
7. Local TV listing
8. Local events
9. Calendar
10. Local movies
11. To do list
12. Email viewer
If you are looking at Pageflakes as a potential container for your PLE, you might consider replacing/adding or creating a new page (and I believe you can create unlimited new pages) with the following flakes:
1. RSS feeds - You can add multiple rss feeds.
2. Box.net - Provides 1 Gig of free online storage for files.
3. Notepad - A place for ongoing notes.
4. Blog - Have your own blog based in Pageflakes
5. Bookmarks - You can add multiple bookmark flakes.
6. "Anything flake" - Allows you to enter your own html or use the embedded wysiwyg editor.
Search the flakes and pagecasts section. Pageflakes pages can be personal or shared. A pagecast is a shared Pageflakes page. There is one by "mlx" (a staff trainer according to her profile page with a special interest in librarianship) with the title "Personal Learning Environments" at http://www.pageflakes.com/mlx/14579658
