You should have this in mind: Facebook was not the first social network, google was not the first search engine, amazon was not the first marketplace. So think of the market whether there is room for some more improvements and/or the market is huge enough to have more than one similar products. How can you solve the shortcomings of the similar product and be different.
Following this point, I think that it probably exist (at least others people had the idea for sure, most probably didn't do anything with it, most likely for the same reason you don't), but if it's not big enough for you to know they exist, you're free to go imo.
Facebook was not the first social network, however if you want to make a facebook clone today you may aswell throw your money right away and save your time.
A very valid point raised by the author. Having worked with multiple api's i can say that developers start preferring that product which has better api docs than the other product which has a crappy doc inspite of having many features.
I was working with PayPal few years back and there are bunch of apis that they provide, but the explanation and usage is so bad that you end up spending a lot of unnecessary time figuring out what to do.
And then i came to Stripe integration. They have beautiful apis which can be integrated smoothly and very easily. I tell developers to follow Stripe's api for writing documentation and examples.
A lot like Instamojo, but Razorpay looks more refined product. Signed up and used the API a bit. Using it was a breeze. Also the documentation is like Stripe which helps a lot.
Congrats on the launch! I am hopeful that recurring transaction problem will also be tackled later on.
It's gonna depend on what filters you're subscribed to I imagine. The anti-social list that blocks facebook spying etc. seems to break pages most out of the lists I sub to.
What i did not get from the site is sneak peek into the design. Do you have a link or something where we can see a demo template design.
