In celebration of International Women's Day we've compiled a list of female innovators in digital journalism and a Twitter list to follow them all.

From established editors to rising stars and social media gurus to techno trainers, these are fifty women changing the face of journalism in the 21st century, as nominated by our Twitter followers and editorial team.

Now, this list is by no means exhaustive, it's not in any particular order except in an attempt at categorisation and we don't claim to have everyone. It is neither definitive nor prescriptive so if you have any further suggestions then please leave them in the comments box. This a celebration! So crack out the champagne (it is Friday after all) and toast to the...
