Is publishing press releases for SEO thorugh newswire sites as effective post panda?

[simon-145328]

Does anyone have any knowledge/thoughts on how leading newswire sites have been effected by Google's latest updates, i.e. Panda? To date this has been a method (alongside others) I have sucessfully used to build links, but the results of late have not been as good for some clients and I'm beginning to question how effective this is - so I would be very interested to hear anyone else's experiences in this area?

I've seen this as still effective in the B2B space, and other sectors that historically release company announcements via press releases instead of a blog.  If you're trying to optimize around B2C and it's not really a news worthy press release it probably won't have much pull.  Google has gotten better and better at correlating search spikes that merit news results and identifying the press releases that merit addition to their search results.  I'd look at press releases and use them in these areas:

1. Regular (Q, H, monthly, what not) Announcement / Core Value Statement
2. New product release
3. Corporate comments on business recognition: awards, analyst review, etc.
