Metatalk has thread tagging now? [more inside]
New Feature: My Ask MeFi [more inside]
New feature: RSS feeds for tags on both mefi and ask mefi (example). Tag pages have links to feeds, or just add /rss to the URL to get the feed.
I changed the way tags are done on mefi. You can now delete your tags and make new ones on your posts. If this works out, I'll extend it to let you tag your mutal contacts as well (and I'll copy the functionality to ask mefi as well). Let me know if you run into any problems. Also, me and jessamyn can add and delete tags on any post and will use this to help keep things organized.
Is there a way to change tags once assigned? In my case, I seem to have misspelled appalachian, but it occurs to me conversations can shift in-thread that an original poster might want to make note of as well.
