Website Marketing

The last two weeks I have learned what would have taken years "back in the day'....I am in my 40's, but wow - even since 2 years ago you have to be really into technology to keep up with todays crazy world of online marketing. I have learned about the RSS feeds, the free pages to publish websites for each of your listings, marketing techniques to sell homes online anywhere in the world, great websites for interacting with realtors all over the country, etc. etc. etc.!! I am EXHAUSTED with the amount of opportunity out there! I literally have about 100 sign in names and passwords for different networking sites, it's terrific, but daunting! Anyone else have any ideas to share?
