This is the latest in a series of weekend posts highlighting a wide variety of applications we think are pretty cool. Most have to do with sales, marketing and productivity. Check out past featured apps here.

Coordinating meetings is enough of a hassle inside a company.  Yes, with the right tools you can see which windows of time exist for your colleagues, but what if you want to do the same for people across multiple companies?  Or determine the best day & time to have your next board meeting?  Or what if you’re just trying to figure out which weekend this summer everybody can get together for a BBQ?

If you’ve endured the endless email threads of “nope, can’t do that” and “hey what about this date” back and forth, you’ll love Doodle.

Simple but brilliant.  Create a page, add several options (days & times) and send an invite email to everyone that you want to be there.  Then each person can essentially click a link and “vote” for the days & times that work for them.  You’ll be able to see which windows work for everyone, or at least work for the highest # or % of people.

No more reply-all back-and-forth email threads.  And I bet you reach consensus much faster too.

Worth a look.
