Which one should you implement? Have you had any success with only one of them? I think you should have both, but concentrate on getting more subscribers to you newsletter, just because an RSS feed is very hard to monetize right now. What do you guys think?
Newsletters have continually offered us the best bet for tracking results, and monetizing our ad space.
Both... rss feeds are great for easy subscriptions, but newsletters give you a way to directly interact, and build a connection, with your readers. If I had to pick, I'd go with newsletters though in a heartbeat.
I would say newsletters because they would be used more often than RSS feeds (not everyone has sites and blogs to repost these items)
Frankly, I like RSS,but I hate Newsletters,for it always disturb me when I don't have interest to see, it, but I can choose to se RSS anytime I want.
