Reddit users seem to be wanting to send a message to Digg. The message they're sending may not be the one they're intending....
Reading through my RSS feeds this morning, I noticed a reasonably large concentration of Diggs focused on Reddit's decision to go open source. Maybe someone thinks Digg's executive team actually reads through the froth?
I guess the real problem it points out is not a code problem with Digg, but rather a people problem, since the Digg system prompts the submitter to verify that the submission is unique. Perhaps these Reddit fans chose not to notice that scads of similar postings had already hit Digg? :-)
