It has become a terrible technology workplace starting at the top.
The c-level's checked out, virtually every decision is delegated to vp's/architects or terribly made.
A culture of continuous dumb decision making: Letting marketing dictate the what is being built. Spending two years to re-create wix. ew & Livebooks. Not a single good product since the yelp like wedding catalog made in 2008.
The flood of middle-management without sound understanding of technology to run the company. The best developers organically hired pre-2014 are leaving, fired, or looking to leave. Those near the top who're staying are either paid absurd money, related to the boss, too loyal to see the faults in the work, or playing it safe to get paid another day.
People have been fired to non-sensical reasons, the HR VP has quit, the new people department is a ineffective.
Every good technology company has it's peak/golden era of growth where good smart people want to work there, they're building things, and having fun. Sooner or later the company grows stale, becomes corporate, and die off slowly from declining revenue growth (livingsocial/blackboard).
The founders already got their money out of ww, they're diversified and invested other private equity companies. Those devs who stay are paid/overpaid enough so while the smart and talented leave because they're sick of it all.
If you're a smart engineer then you should probably go work at one of the many other DC Tech startups. Weddingwire is bureaucracy, corporate politics, and bad management at this point in 2016.
