As a heavy handed tagger, I recently ran into major performance problems with Live Writer having to store "too many" tags. It would take 8 plus minutes to upload posts, and that just wasn't happening.
I ended up deleting all but the most bare minimum of tags, and LW performance has significantly improved.
I'm curious if anyone out there also uses Live Writer, and/or knows of some kind of fetch-custom-fields workaround that can be worked into a post and (invisibly?) embeds tags that bypass Live Writer?
This maybe a very simple thing that I just can't formulate, but I'm a Photoshop geek, not a coder.
