It seems to be the season of silly things for me. Today I did a bulk node import from an old blog into this blog. But what I failed to do was turn off the Twitter update status option in the twitter module for Drupal. So, be warned. Unless you want to repeat my stupidity remember to turn off the Drupal twitter Module update option when bulk importing nodes.
To those who received all 192 gratuitous updates in twitter, my humble, humble apologies.
