Throw that in with more features and a better service, the choice is obvious.
If you were working on these features before they started bugging you, you'd have them out by now
If you were working on these features before they revealed them, you'd have something to show by now
If you weren't, then you were just waiting for someone else to innovate so you can steal their ideas
Since you don't have functional features or even demonstrative functionality we can only assume you were incapable of coming up with them on your own and had to wait until someone else showed you what to do. And now you're just sitting here wasting everyone's time by somehow claiming superior functionality by cloning someone elses
at best. You could have at least had some dignity about it, and then some small amount of respect would remain for you from the general community, but you destroyed that too.
Any credibility you had is long gone. If you're not going to give up, you'd better at least shut up and get to work. Like Lub said - both before and after showing his hand - you've had more than loving long enough to enhance your service. The fact that you didn't even look into doing so until an alternative was announced shows that you don't care about your customers.
