One option is to pick a tool which lets you email anything and everything to it.

In my case, I use Evernote to consolidate all my electronic inboxes. Everything gets emailed to Evernote: Web clippings, emails I want to save, emails I need to create projects/next actions for, links - you name it. Because Evernote can hold/parse files too, it's a great storage locker for electronic stuff which needs filing.

Then a couple of time a day (depending on how busy I am) I go through Evernote's inbox and file/delegate it, or convert it into an action or project in Omnifocus as required.
