We wanted to be different from those other sites and focus on a niche, which is golfers. Also, we have some cool features planned that are directly related to golf.
Without knowing too much about these other sites, what sets DecideOnADate apart is that we focus on driving a group towards a date that works for as many as possible and doing so with the least amount of effort as possible on part of the organizer. Our goal is for the organizer to create the event, and then not have to do a thing. We will notify them when a date is decided on.
You're right! Previously users could create an event without creating an account, but I was worried that people would abuse the system. Therefore I added mandatory accounts and email verification. Thanks for the feedback.
I might subscribe to the oft-repeated mantra to not fix what isn't broken, especially considering that users cannot view other users' calendars, so mediocrity or spam is not of a major concern to you.
That said, awesome app. It's certainly a problem I'm sure many are constantly faced with. (I know I am) My first impressions though include a lack of detailed info (how does it work?) compounded by the inconvenience of making an account for the site. (I still haven't registered)
Edit: As for a small change you can do right away, I feel like users would consider "John Doe" <jdoe@example.com> more intuitive than "Invite Name" <Invite Email>. (Consider making the name optional altogether or just having a more intuitive input method, like multiple <input> prompts)
Each release didnt catch on and it was getting harder and harder and more complicated to continue. After learning about the mvp I realized I should have something even without all the features. Once everything was removed it became clear the best conversations were happening when there was 3 people and thats all that mattered. So the mvp was 3 people can talk, anyone can lissn. :)
