My review:
This service is cool and will probably work for indexing. But i could care less about that - anyone can get indexed without paying a monthly service fee.
My "intro" tweets are flowing in and they look great! I didn't put URLs in them... it's basically 100 uniquely spun "Hi welcome to my new nutrition twitter account". So far so good.
But where I want to see this service go is for SEO reasons. People are starting to see that Facebook Likes and Tweets are counting towards SEO, and you can POSSIBLY mask xrumer runs with lots of Tweeting (this makes sense - if they're talking about it on the forums, they're gonna be tweeting it too - otherwise... it's shady)
The problems if you want to use this for SEO:
1. You cannot schedule tweets. I wanted to make a nice, natural bell curve of links. 5 posts now, 10 posts in 6 hours, 15 posts in 10 hours... etc.
2. Following isn't good enough. What would be great is if I could dump in a bunch of famous, niche-related twitterers who I can have these accounts randomly follow a few of on some slow schedule. Nice and natural. This will slightly help with the indexing of my accounts and thus my tweets to my URL. But with this, you have to add one at a time and randomly choose from your accounts. Not bad, but annoying.
Now, everything I want to do can be done manually (manually tweet my links in with the users in sequence), and I will do just that. But... it could all be automated and BE AWESOME. That would keep me as a monthly customer.
I'm not the target demographic but I think it's time to start looking at the SEO possibilities:
