I'm making my game Lead Wars FREE for the first time on 4th July, and was hoping fellow indie devs could follow suit and share a Twitter hashtag, #INDIEpendenceDay. Then we can easily find and retweet each others' links to other free indie games. And maybe hopefully various game sites and bloggers can use it to see who's got a freebie promotion on for this holiday. Because it's a day all about American FREEdom (from rule by those pesky Brits such as myself!), I think it's most suitable for this to be used for free give-aways, not for a regular sale. There will of course be loads of sales on for 4th July, and I of course can't stop anyone using the hashtag for a normal sale but hopefully this combined effort will help us zero-marketing-budget indies can get a look in during this time I've scheduled in the price change in iTC to go free on the 4th, but I suppose you can go free when and for how long you like (I'll probably leave it for a few days).
