At 5:50 AM EST, I can see 4 posts from Techcrunch in the front page of HN.

1. Exposed: Facebook’s Secret iPhone Photo Sharing App (Which Looks Amazing) - 29 points/11 comments

2. Troubled Startup Color Loses Cofounder Peter Pham - 155 points/77 comments

3. Why All The Daily Deal Hate? - 56 points/22 comments

4. Investors Pump $90 Million Into Airbnb Clone Wimdu - 33 points/21 comments

I think it has been a long time since I saw these many posts from Techcrunch hitting HN's front page. Is it a comeback of the Techcrunch mania?
