No. Facebook has become one gigantic RSS feed. It's blog post after blog post by pages trying to get traffic off FB and on to their sites so they can sell advertising, lead people to affiliate offers, etc.
All the most successful, biggest FB pages aren't doing any silly "socializing" or interacting with their "consumers." They treat their fans like cattle and market blog posts to them many times an hour in order to get them to their website. Every minute spent answering a stupid fan comment or message is time spent away from creating the next blog post or optimizing your site, which is money lost.
2. Myth: Facebook is all about creating viral posts that big pages will share and get you a gazillion new fans!
No. Big, influential pages rarely ever share anything anymore by other pages. That was the old days when you would create a meme and hope for a page with 10 million likes to share it. Nowadays, a huge page will simply repost your meme rather than share it - which results in no new likes for your page. Or if you post a blog post of some funny Youtube video or news piece, then other blogs will just write their own on the same topic rather than share yours.
3. Myth: You can get lots of free likes without advertising.
As I said in #2, the days of huge pages sharing your posts are over. Therefore, getting 50,000 new fans overnight is a pipe dream. Yes, you can get a conistent trickle of a few hundred or a thousand new fans a month by posting consistently, but at that rate you're getting left in the dust because other pages who are spending money on FB ads day in, day out are going to gobble up a lot of the fans at a much faster rate.
You simply need to spend money if you want to be a shark on FB. If you want to wallow around with 10k or 20k fans, then whatever. If you want a page with 500,000 fans, forget about it without some serious ad spend.
