Is it me or does Twitter just feel like another way of big brands and companies pumping out the crap in their email newsletter?

Even though I don’t follow brands I do send them a lot of ‘@’ messages, whether it’s a question, feedback, or mostly when I’m pissed off at their service/product. What I’ve noticed is that out of 50 big brand messages I’ve had 2 replies, one was a week later by Dell and the other was 2 days later by First Direct (although they ignored my reply after that).

Is it too much to expect such a easy way to communicate with a brand to be rewarding?

What’s your experience?
