The old Microsoft Live Writer had a really nice feature that I miss. You could have a list of words and phrases that, when typed into a text, would automatically cause a link to be created to a URL that you had chosen.
Let's say that I often write movie reviews. I could register the phrase "John Wayne" so that every time I wrote it in a post it would link to John Wayne's page on IMDb without me having to bother about it.
It would be great if you could include such a feature in the online post editor. Live Writer would only do the link on the first ocurrence of the text but that could perhaps be a setting
