Topic: A competing/concurrent approach
I have now used Taggedfrog for a few days and quite like the experience. allow me some suggestions for your further development:
Have a look at http://www.jannemijn.nl/gui.pdf. This comes from the same guy who developed FolderView. When integrating with MS Office, you may want to look at his approach. I like they way he shows the cloud inside an Office "Save File" dialogue
Even better would be to use an existing function in Word to highlight words or phrases ( the bookmark tool? ) and automatically insert those in the tag cloud as associated with this file.
Doing the same in a PDF file is a little harder as so many people use Acrobat reader or freeware like cutepdf, all of which have no editing functions.
Are you planning to include webpages? Will you make a local save? in html? txt? ave a look at www.surfulator.com for a (free trial- paid) tagging engine which began its functionality on webpages. some nice features.
I expect that with increased modes to create tags, there will grow the need to manage and merge tags. Like "tag" "tags" and "tagging" merging into "tags"
I've just invited you on Linkedin; have a look at "tagging on the fly" in the "Answers" tab, for some other recommendations
