Dear Lazyweb: How Do You Deal with Blockers?

After reading a number of post on the Ubuntu and KDE planets, addressed to Dear Lazyweb.  I’m not going to be lazy and not do research on this topic.  Rather I am interested in hearing how people deal with certain problems.  So I’m going to turn the blog over to you guys and gal, and get your ideas.  Please prove to me that this crowdsourcing of ideas idea really works. 🙂

So dear Lazyweb,
How do deal with blockers?  Blockers being larger/enormous tasks, that prevent your project going forward organically.

Thanks in advance.
