Please fix broken link and update blurb

Could someone with edit rights in the wiki please fix the broken link for
Metamarkets that's on this page:

https://cwiki.apache.org/confluence/display/KAFKA/Powered+By

The right URL is: http://metamarkets.com

Also, if you could update the Metamarkets blurb to:

"We use Kafka to ingest real-time event data, stream it to Storm and
Hadoop, and then serve it from our Druid cluster to feed our interactive
analytics dashboards. We've also built <a href="
http://druid.io/docs/latest/Kafka-Eight.html">connectors for directly
ingesting events</a> from Kafka into Druid.

Thanks!
