Many venues should not mean many journals. Journals are only one possible venue for your work and by limiting yourself to them you limit the potential reach of your work. Other scientific outlets are conferences/congresses, presentations to universities and societies, scientific blogs and magazines. If you are planning on publishing your work then one potential route would be to present it at a conference, either as a poster or an oral presentation, before writing it up for a journal article. Once the work has been presented at a conference it can become part of a talk to give at other universities or societies, and this talk once it has been given several times could be written up either as a review of the work of your lab for submission to a journal or magazine, or published on a blog.
By presenting the work in these different ways, a number of different audiences can be reached and introduced to your work. They can also be excellent as opportunities to network and grow your circle of associates, possibly helping to bring about collaborations and secure funding. I would therefore suggest that if you are early in your career you should be trying to get your work seen and heard of. You might not be able to be invited to present your work to another university or interested group. However, you should be submitting your work, once it has reached sufficient quantity and quality, to congresses, or offering to talk about your work to undergraduates or other research groups you know. These might also have the added benefit of providing new thoughts and ideas on your work from people with fresh perspectives, as well as identifying any holes that need to be looked into.
Another way to be able to talk about your research with more people is to volunteer for societies and attend local interest group meetings. This may bring you into contact with influential people you will not meet in any other way.
