Does it catch you? Answer in detail!

Answer 1

Implementation dependent. If you make it cool and convenient, they will use it. If dull shit (hereinafter UG) - no one will waste time.
For 10 years of practice, I came to the conclusion that the main thing is the quality of implementation and support, not the idea. Even on an idea as old as the world, you can always cut the jackpot if you work with high quality. Even opening a bakery can already earn money if you approach it wisely.
In principle, similar (aggregation) services and programs already exist. But they are not convenient, so no one uses them.
If you can do it well, do it. If one more UG - it is better not to waste time.
