If you use twitter at all to discuss MTG-related topics, feel free to post your twitter handle in this thread for others to follow. I created an MTG twitter account and will be trying to stay reasonably active on it, so add KDY_MTG if you have any interest in this! Would be nice to get some Kelowna folks' views/opinions on stuff.
I'm @bmkmedia on twitter. FYI, my tweets will be 50% magic, 25% humour, and 25% random musings.
I don't tweet about Magic, but a really good laugh is the old @MTGStormCrow account, some brilliant material there.
