To query or not to query that is the question

I know in my last post I lamented the ago old quandry of "you can lead a horse to a book but you can't make him read it or review it, even if you beg."  In that post I made a snide comment about hitting up bloggers and reviewers smacking of querying agents. And it sort of does, but with that being said, I went and submitted to 3 agencies this week. One gave me an immediate rejection, which was highly insulting, especially considering I just finished reading one of their recent releases and was completely underwhelmed (Between the Devil and the Deep Blue Sea if you have a morbid curiosity). So I come off that book thinking "my book is better that that one!" Yes, I admit to a certain amount of bias, but still, I seriously got the rejection less than an hour after I sent the query email.  Yikes! 

So I am coming at the problem of getting my book out there on 3 fronts now.

1. Bug all my friends and enemies until they read Safe Distances and review it just to shut me up,
2. query agents at a rate of 3 per week,
3. publish on all the ebook formats (got the nook version up this week and I am working on the iBook version today) and take advantage of any free marketing advice and tools. 

Meanwhile book 2 is nipping away at my brain, begging me to beef up a couple of sceens that I have not properly harvested for maximum tension and screaming to move forward with the story.  Add to that the need to make up posters and negotiate the format and times for my book signing at Cafe Java. Don't know if I coming or going, and I really want to take a week off of work to sleep. 

Hey does anyone have any idea how to get twitter followers so that becomes more than me tweeting to myself and a couple of loyal friends? How is twitter a viable marketing tool? I am flumoxed, but I can still pull a good word out of the hat when I need one.
