For blogs, the 3 regulars I read and I think are quite popular are
http://5cc.blogspot.com/ = 5cc (five chinese crackers),
http://www.septicisle.info/ = Obselete, and
http://enemiesofreason.blogspot.com/ = enemies of reason
All of those frequently pick up on Mail/Express stuff and they all have a buttload of links to other blogs which I haven't looked at.
If you want to include links to parody DM,
http://uncyclopedia.org/wiki/Daily_Mail = a link to uncyclopedia's page,
http://charlieharvey.org.uk/daily_mail.pl = story generator,
http://vodex.net/mailmaker/ = front page maker,
http://www.urbandictionary.com/define.p ... daily+mail = definition from the world's best dictionary
If you want to include links to news parody sites,
http://www.thedailymash.co.uk/ = the daily mash
http://www.thespoof.com/ = the spoof
If you want to encourage people to use more news sources, instead of relying on just one (whether it be mail, express, sun, guardian or fishing weekly), I'd use
http://news.google.co.uk/ google news.
I'd also suggest linking to data sources, such as the reports that the mail quotes. Sorta to encourage people to look at the source info for themselves. Course I doubt many mail addicts will be on this site but you never know.
Not got any links for those at the moment but I'll dig some out tomorrow if I remember.
And lastly I'd link to navigor. Just because it'll piss him off and be really funny
