Loren over at Incremental Blogger has posted a screen shot of WebCamNotes, an ink blogging application and a few others like Julia Lerman are working on them as well. I think the concept of ink blogging is extremely cool. As somebody that believes very strongly about the potential of that tablet pc, I think ink is a great format of input, but I have mixed feelings about the posting ink as an image. While there are certainly some fine examples of expression through the pen, there are issues with two of the best things about blogs are the power of search engines and RSS. I strongly buy into the Scoble view of news aggregators as the only way to read blogs effectively.
Now if we could effectively use ALT image tags to hold the converted text of the ink and hopefully help with the search engines. Another option would be do have blog engines return text to searches. I don't know if this would work well enough or not, at least until somebody creates a search engine that could somehow index and search “digital ink” like is capable within OneNote, but I think we're far from this. The second thing would be for a news aggregator to read this as well and optionally display the text.
For now I think that we're left with Ink Blogging being cool, but a few issues need to be worked out.
