With the push to go paperless, tools to annotate both web pages and documents are becoming more and more important. I’ve blogged elsewhere about annotating .pdfs but just read this post about annotating websites and documents. A lot of these sound interesting, especially the highlighting (as opposed to the annotating) ones, e.g. In-Focus which lets you highlight a part of a website and black out the rest of the website, but otherwise I’m wondering the advantages of these over GoogleDocs and/or Word’s track changes. I’ve not used any yet, so as I do I’ll let you know if I answer that question. Anyone use any of these?
