Twitter fails as a promotional tool?

Colnect has joined Twitter less than a week ago using a few Twitter profiles:
* Colnect news Twitter @colnect
* A personal Twitter for Colnect's manager @AmirWald
* Automated feed reporting new collectibles in Colnect's catalogs @ColnectCatalogs
* Automated feed on Colnect's catalog edits @ColnectEdits

During these days 28 visits came to Colnect from Twitter, a meager amount in comparison to the number of "followers" and energy invested. The bounce rate (visitors seeing a single page and leaving the site) was incredibly high as well. In comparison, a few posts on a relevant forum resulted in hundreds of relevant visits (with much lesser bounce rate).

It seems a lot of people use Twitter to self promote and so it's more of a bubble where "followers" is a rough indication of the number of people who will actually read anything of what you write. My guess is that for most people, a small percent of their "followers" actually read more than 5% of their tweets. Though some people think of it as a useful personal tool, it doesn't seem like they dominate Twitter.

Though less than a week may be a too short amount of time for a verdict, results so far are very unsatisfying. In the future, the automated feeds may be of use to some of the addict collectors on Colnect. Let's see what the future brings.
