Same thing happened to me recently, didn't seem to have any effects on the SERPs on both Yahoo! & Google though. Shouldn't have to worry too much I guess.
Y! Link count periodically ( so far noticed it happen twice per 24hr )drops, then reindexes back to normal within an hour or so. Bing is the reason 'nuff said.
Yes I think its the blog commenting this, because I have had over 500 links disapear all of a sudden and the only thing I can think of is that some of the websites have top commenters and I have dropped out of those. Keep building links, as long as your main keywords are safe in the serps, I dont think you have anything to worry about. I am not worrying yet anyway.
No, it`s an error from yahoo. Sometimes my backlinks are 10k sometimes 600...lol Just an error, it`ll be back soon. Regards,
