1) Don't engage in a million conversations. Too much to handle. Too time consuming. And you will get nowhere.
2) Don't quit a convo too fast. Ok so it's a bit boring at the beginning - because ^ we're all consumed by 200 other convos - which is why most convos tend to last 5 lines, and get you absolutely nowhere.
3) Ask the right questions. Don't ask "what's up". The reply will be "not much you?" and the convo will pretty much end right there. Don't treat this like MSN Messenger. This is a DATING app. Get to know the person and figure out if they're what you're looking for ASAP.
4) If you're not feeling it, STOP TALKING TO THEM. Just be polite and tell them they're not exactly your type. No need to keep convos going for nothing.
5) Finally, the most important: as I said in the Tinder Tips Post, GO ON A DATE ASAP. If you wait too long, it's just never gonna happen, so whether you're a guy or girl, ask to meet the person within 2 weeks of talking, and in a public place of course #safetyfirst
