There is more on this over at
http://tiddlywiki.org, but I find new
TWs all the time using search engines. The important thing to
understand is that they will always point to your page, not to a
specific tiddler.
This is a good/bad thing. Search engines treat a TW as one page, so if
you fill a TW up with very specific content (Reviews of 897 different
types of cheese, covering one cheese per tiddler) then you will get
lots of hits from folks seeking cheese who will be happy they found
you. If you fill a TW up with content that covers computers, cheeses,
underware, your day at the beach, the plot for the bodice ripper you
are writing, thoughts on future uses for TW, and your poetry then you
will get hits, but the visitors will have a harder time understanding
why they got directed to your site.
