All proceeds made on January 20, 2010 will be donated to Haiti. You get great software, Haiti gets financial help in its time of crisis.
Buy any of the software on that page tomorrow (Wednesday) and the developers will donate the proceeds to charities for Haiti relief. (Huge thanks to Justin Williams and Garrett Murray for organizing this.)
I’m participating with Instapaper Pro and donating to Doctors Without Borders (MSF).
Of all of this great software, I already own and love Billable, MarsEdit, SubEthaEdit, and Tweetie, I’m definitely going to buy Acorn and Clipstart, and I’m eyeing PDFpen and Tickets. Look through the huge list — I bet there’s something you could use.
