Google is showing fewer and fewer of backlinks

[smokey99]

Hi,
Can anybody tell me why G seems to be showing fewer backlinks into my site everyday?
Yahoo is showing 250 + and unchanging
Google previously showed a hundred or more 6 months ago, but seems to be showing less all the time.

It doesn't seem to have affected my serps or PR, but I am down to 2 links in Google!

Googles is doing some real weird crap these days.

Should I worry?
Anyone else experienced the same?

Thanks
Smokey
