I just created a new search engine, Wiki Search, which indexes this content:
- Wikipedia - the open source encyclopedia
- Wiktionary - a wiki dictionary
- Wikiversity - opening minds through learning
- Wiki Books - your open source for eBooks
- Wiki How - the Mr. Fixit of wikis!
- Wiki Index - an index of wikis
- Wiki News - today's news as posted/edited by netizens
- Wiki Quote - quotable quotes!
- Wiki Species - a directory of life!
- Wiki Travel - your online travel resource
Note: Wiki Search site addition suggestions are welcome; however given the number of wikis on the web (Google it!), my focus is general reference wikis. This search index also includes my blog.
