Things I pay for online

Scalzi posted a list of all the subscriptions he pays for online, and to me it looks a little extravagant. Here's my list:

• Flickr pro account ($25 per year? something like that)
  
• Netflix including online access ($17 per month)
  
• Librarything lifetime membership (I think it was $20; that's the kind of fee I'm willing to pay)
  
• My domain and hosting (I paid for 2 years in advance, I think. $6 per month?)

Things Scalzi mentioned that I use but don't pay for:

• Livejournal x2
  
• Newspapers (NY Times, Boston Globe, others)
  
• Encyclopedias (while I was teaching, I had full access to the Simmons system which had every academic source you could think of; now I use the BPL and my local library network online when I need a reasonably vetted resource. Mostly I use wikipedia, tho)
  
• Streaming music (various places)

Things I've considered paying for:

• Metafilter account: ($5, I think lifetime? I should just do that)
  
• Wikipedia donation drives

Is there anything you pay for online that you consider totally worthwhile?
