The MovableType Bookmarklet makes blogging any website a snap, see our Blogging with the MT Bookmarklet summary.
But by pure accident, I discovered this tool has an added bonus.
Not only does it build a hypertext link to any web site in view in the blog entry form, if you can highlight any chunk of text on the web page, the bookmarklet can transport that test as well to your new entry.
This is what you could use to pull a small quote from any web page when you are commenting about it.
I will harp again, but be sure to somehow indicate a difference in a blob of text taken out of another site from your own voice.
There is way too much “regurgi-blogging” going on- people that create a new blog entry and simply insert en masse, some text lifted from another site.
