MAJOR may be too tame a word. Furthermore there are several enhancements the community could make to support retail data and retail recommenders. For one thing without public data a *public* cross-recommender will probably not get built.
The cross-recommender needs to separate actions types and use them in slightly different ways so it is important to have a data set with user's purchases but also views, add-to-cart, impressions, purchases in groups (shopping carts)--whatever events are available with anonymized user IDs. This data set would be significant in getting new techniques into the community and therefore back to people like you.

Movie Lens is way too small to be meaningful any more. Wikipedia articles and Stackoverflow tags are not retail data! By all means, post some real retail data, if you can. Meaningful sizes would be appreciated: millions of customers, thousands - tens of thousands products.
