I get plenty of email spam... but Gmail does an admirable job making sure most of it doesn't hit my inbox. My new annoyance is, for lack of better terminology, "web 2.0 spam". My inbox is filled with junk from Twitter, Disqus, Vimeo and all of the other services that I use frequently... all getting increasingly worse (particularly over the last two weeks).. It's brutally annoying because, unlike email, this spam is usually visible to more than just my eyes. Whereas email spam clogs *my* inbox - these new forms of spam affect my public arenas... sometimes for personal content (like my blog) and other times for company content (like InGameNow, Widgetbox, etc).
And as services like Twitter and Disqus continue to grow - the spammers get more sophisticated because the value of spamming increases. It's no longer Viagra and Acai Berry ads - it's silly link-bait being used clearly for SEO purposes. Unfortunately that too is problematic in ways that traditional spam isn't... enough SEO spam can have negative affect on my sites as well.
