House churches on the grow...is this good?

I was raised in a house church.

Worked for me!

But is this a good trend? Barna:

The new study, based on interviews with more than five thousand randomly selected adults from across the nation, found that 9% of adults attend a house church during a typical week. That is remarkable growth in the past decade, shooting up from just 1% to near double-digit involvement. In total, one out of five adults attends a house church at least once a month.
