I really like how responsive they are with the Rapid Response function. They'll update journalists and outlets as needed, including finding UVMs/circulation figures. It's nice to have another person to help you out when you need something. Also, the national media/NYC based media is pretty well built out, and is updated somewhat regularly.
The local database - even in places like LA, can be very outdated. Journalists, entire outlets, circulation/UVM figures and freelance writers are often missing. Many times freelance journalists have phone numbers associated with them that are just to the main desk, and thus not useful if they do not work out of the office. Many people have addresses that default to their main publication, when in fact they're based in another office, work remotely, etc. With this in mind, you have to be very careful if you're sending anything by mail, and are likely to have the package returned in many cases. The search function is difficult to learn as well. It used to not let you export blogger emails, but fortunately that has been fixed. Another tricky thing about Gorkana is that it will not let you export circulation in many cases and doesn't let you search by DMA.
Weigh the benefits vs. the drawbacks.
We use Gorkana to build media lists and locate contact information for editorial contacts.
