How to make my papers accessible to other researchers?
From the context of your question, I assume you are a computer scientist graduate student.  (Computer scientist because you mention DBLP, and graduate student because you're worried about people finding your research quickly.) My answer is specific to computer science, especially the first two points.


Just post your papers on your web page already.   Among other things, posting your own papers will allow Google Scholar to find and index them after only a few days. Despite scary legal language to the contrary, neither ACM nor IEEE (or SIAM, or AMS, or Springer, or Elsevier, or...) has any interest in suing individual researchers for providing copies of their own papers. 
Post preprints of your work to the ArXiv and/or your institutional preprint server.  Again, despite scary language to the contrary, granting a license to the ArXiv to publish your papers does not deprive ACM or IEEE (or SIAM, or AMS, or Springer, or Elsevier, or even ACS) the right to later publish peer-reviewed version of your papers later.  Many publishers explicitly allow you to publish post-reviewed but pre-copy-edited preprints on the ArXiv and similar servers.  Posting camera-ready versions is technically illegal, but neither ACM nor IEEE has any interest in suing individual users for such violations.
Post publication announcements on Facebook/Google+/Twitter/your blog.  Yes, this works.  Really.
Give lots of talks.  At a minimum, you should give talks about your results in an appropriate local seminar.  But especially for really strong results, you (or your advisor) should also arrange to have yourself invited to a few other institutions to give a talk.
Send copies of your work directly to a few colleagues.  Just send them email with a link to your web page.  (Don't blindly send papers as attachments; remember that some people read email over the phone and pay by the byte.)  But don't just spam the whole world.  Limit your email to the small handful of influential people that you are sure will be interested — other researchers working on the same problem, people whose results you directly improve or extend, your advisor, and—if you're nearing a point like graduation or tenure where you need letters—a few potential letter-writers.
Take the long view.  It really is not important that see your results RIGHT NOW THIS MINUTE ZOMG NOW NOW NOW !!!!111¡¡¡CXI.  Relax.  Yes, DBLP and other indexing services operate with a delay of several months.  (Although my impression is DBLP has gotten faster, thanks to some outside funding that allowed them to hire more than one human being.)  And yeah, that's frustrating.  But in the long run, those few months of publication delay are not going to make a bit of difference.
