I don't think doing interviews to gamer sites hurts at all. However I would tell sites who are getting exclusive information that the release of information on ks and that the information will be published on ks by x date and y time regardless of when they decide to publish. So their exclusivity is dependent on the time schedule.Hopefully this delayed PCgamer article has taught him not to rely on such outlets with the clock ticking. The best place to post new information about his game is on the kickstarter page and he should be posting as much of it as he can as soon as he can. The more excited he can get people about the game now; the more people will spread the word. Going forward he must do.
I agree getting the information on ks is psramount. Interviews are just a way to try and let more people know about the ks. However they can't impede the information roll out of a limited funding cycle. Them publishing late and holding up information negates their value significantly.
I don't know much about pcgamer but looking at it over the last few days they seem to have two or three main stories a day. So it is not like it is a niagra falls of stories. Which is fine, but being three days off or more on delivery means they either don't care about or understand the time component.
I do think interviews with game sites can be a tool that can work in the ks environment but you have to approach it more aggressively and absolutely with publishers in terms of deadlines and roll outs.
In this limited and precise funding window all information deadlines need to be hard and if other sources fail to meet those timelines the information should still be presented. If it were me and pcgamer did not deliver by early afternoon tomorrow I would already have an update written and ready to go up early afternoon tomorrow. If pcgamer gets upset they will have to get over it. As will all future interviewers. In fact I would be following up with all other pending interview release points and push for hard commitments and give them drop dead deadlines for when you have to publish their exclusive information without them.
Can't really sorry about some web page editors getting their feelings hurt when you have to be aggressively maximizing each day.
