I've read many of your comments below, and you seem absolutely convinced that the only way to get coverage is by having contacts in the industry, or by being in Silicon Valley.
Well, I can tell you as somebody who is definitely not in Silicon Valley, has never raised money, has no contacts with tech blogs and has been featured on TechCrunch, TechRadar and others, that it isn't only about connections.
You are absolutely convinced that your app should be covered by these blogs, but the blogs are covering apps that are new/different/special.
I don't mean to be harsh, and it doesn't mean that your app doesn't have a market, but the 'features' you are touting about text-only, less data usage, less costs, etc. Aren't selling points for the general population. I live in Canada where data usage costs are MUCH higher than in the US so you'd think that I should care about these things. But the plain facts are that css, images, etc. are barely a minor percentage of data usage. Video uses data, music to a lesser extent, skype, etc. These are the data hogs. You've created a product that might fit a very small niche, and you sound like you are trying to get the major outlets to cover it. That isn't going to happen unless you can pitch them a story about why it matters, and where it has made a difference.
Think about how your app has actually helped somebody do something that they couldn't do otherwise. What is the true benefit of text-only web? Make it personal.
By the sounds of things you may be trying to pitch your app based on 'features' which rarely matter. Twitter wasn't the blog darling because they only allowed 140 characters, they got all the attention because they allowed you to communicate quickly with a large group of people, and the brevity made the content easy to digest. 'Tell your friends about the great band that's playing at xyz, with Twitter'. What would your headline be? Is it interesting and would anybody care?
You've got to work on your marketing, though I also think you need to work on the reason your product exists.
