Twitter has become an excellent tool for SEO. Now days many seos are use twitter the right way, Those guys have learned methods to use sites like twitter with lot of respect and I have seen some good discussion twitter between people in seo industry. At current lots of people using myspace, orkut, facebook and many other social bookmarking sites like digg, del.cio.us, reddit and many more. But there are lots of people using twitter first. Some SEO have 5000 of followers which itself is a very good sign for SEO.
Today the awareness of people about search engines is huge. Only good SEO companies and SEO guys survive in this ever increasing competitive industry. Other people to look out for in twitter are Danny Sullivan, Jeremy Zawodny and lot more. I don’t recommend you block anyone who wants to follow you unless you feel they are really spammy.
