Ask HN: Travel Tips

I am a simple data analyst who has nothing to do nowadays and i just want to build something. I am so new to this ecosystem as a player, i am just "looking on" for years from bench.

I have travelled in Europe last year and have seen so many places. Before journey, i have collected so many tips from 4sq, yelp and tripadvisor. Now i want to build a website and mobile app about "handcrafted tips" for specific city and/or districts (of course i want to monetize my project, even if it does no flow, at least it drips; this is my first time). i will collect the tips from this sites again which i haven't expreienced but trusted ones beside that i have experienced. i will summarize the tips and give link to this sites (so user can see the original tip from it's original site). basically, that's all.

I don't want to be faced with problems later (because i'm summarizing some tips from the site and giving exact links; for example : " must visit : clinton baking street! (http://4sq.com/1fC4ymP) " so how should i approach to this issue?

Thanks.
