I would say that this is untrue. How much (or how little) people care about what you say is simply tied to what they've heard from you or about you in the past.
A framework project helps with this, because it presents a history of your work - but it only helps if other people are actually using the framework. That same history and reputation could be established by authoring a widely-used library, or by voluminous contribution/collaboration with open-source projects.
In some cases, even just imparting your knowledge can establish the positive reputation. This is where blogging and speaking at conferences (and unconferences/lightning talks, to start out with) can help.
